9. stREam ecological valuations for the karamu stream catchment

Mr Sevicke Jones introduced Mr Adam Uytendaal, the new Team Leader/Principal Scientist Water Quality and Ecology to the Committee. Mr Uytendaal gave the Committee a brief outline of his work experience in Australia and said he was extremely happy to have the opportunity of now living in New Zealand.

Mr Stansfield gave a Powerpoint presentation which updated the Committee on stream ecological valuations that had been occurring within the Karamu Stream Catchment and also outlined the potential uses of the SEV method which examines the integrity of stream ecological functions at a given site and provides a framework for the application of numerical values to describe the level of impairment of ecological functions operating at a study reach. Mr Stansfield noted that as there were not any reference streams in Hawke’s Bay, and that a reference stream in Papakura, Auckland had been used to compare each test and generate the SEV scores,

Mr Stansfield advised that all the information gained from SEV scores would be useful to Council to assist in future strategic approaches for ecological enhancement.

Responding to a question, Mr Stansfield said the length and width of the riparian margins would depend on what was hoped to be achieved when enhancement projects of streams were undertaken and also the topography of the stream area.

Mr Black noted that Maori are more concerned about what is happening in their own little area and if there were problems they would expect remediation to take place in that area rather than fix the problem out of their area.

The Committee discussed the SEV method and agreed that it was a useful tool for policy development, however, expressed concern that it may be too technical for whanau and hoped there would still be opportunities for whanau to participate in future cultural policy assessments.

The Committee also discussed hard engineering solutions which had been introduced by Hastings District Council and the possible effects these may have on stream ecology.

Resolution:

That the Committee receives the report titled “Stream Ecological Valuations for Karamu Stream Catchment”.

Black/McGregor

CARRIED

Councillor Remmerswaal and Messrs P Paku and M Apatu left the meeting at 10.40am to attend the funeral.

10. RECREATIONAL WATER QUALITY MONITORING REPORT

Ms Madarasz-Smith gave a Powerpoint presentation and updated the Committee on recreational water quality at key recreation sites in Hawke’s Bay which included the results for the 2009/2010 season. These results indicated a 95-100% compliance with national guidelines at marine sites with exceedances related to 1 February 2010 flood event. Freshwater sites achieved 90-95% compliance with exceedances also related to heavy rainfall. Lagoon sites achieved between 85-95% compliance with the majority of exceedances a result of heavy rainfall.

It was also noted by the Committee that statistical analysis of the last ten years of data indicated that water quality at most areas had improved over this period however water quality at Porangahau Estuary had declined. Three of the five shellfish gathering sites also exceeded guideline values.

The Committee expressed concern that on occasions there was a lack of signs erected in areas which were currently unsafe for the community to use and requested an explanation of the communication process involved at these times.

Ms Madarasz-Smith advised that bacterial numbers had increased at Porangahau Estuary and staff were currently undertaking investigations to find the cause for the increase. It had been suggested that wastewater discharges and land management practices in the area could be the causes. The test results to date had not shown any metal residue from the landfill present.

Resolution:

That the Committee receives the report titled “Recreational Water Quality in Hawke’s Bay: Review of the 2009-2010 Recreational Water Quality Monitoring Programme.

9. update on current issues by ceo

Land and Water Forum

Mr Newman advised that the Land and Water Forum which included iwi members was currently preparing a report on fresh water management issues. This report was due for release at the end of August and no doubt will have an impact for Council.

Section 36 Charges

Mr Newman updated the Committee on Section 36 charges and outlined the process why charges would be levied across consent holders. The current results are based on defined zones within the region.

Holding Company Structure

Mr Newman updated the Committee on the proposed Holding Company structure to be established by Council and outlined the purposes for the proposed company.

Treaty of Waitangi Settlements

Mr Newman reported that there was ongoing debate with Central Government around the Ngati Pahauwera Deed of Settlement which could have implications for other Hawke’s Bay treaty claims.

Feasibility Study – Ruataniwha Basin

Mr Newman reported that the geological phase of the feasibility study had been undertaken on the Ruataniwha Basin and only 2 out of the 6 proposed sites were suitable. Sites included within the first 14 selected were currently being re-evaluated.

CHB Wastewater Project

Mr Newman advised that Council had investigated additional land where possible irrigation could take place and that the revised consent would include an investigation of an integrated wastewater system to land mainly forestry and pasture. There was potential for Council to move some water out of the river onto land particularly in the summer time.

QSM – Haami Hilton

Mr Newman on behalf of Council congratulated Mr Hilton on his receiving a QSM awards in the recent Queen’s Honour’s List for his services to the Community.

Resolution:

SUBJECT: Update on Ruataniwha Cultural Impact Assessment

REASON FOR REPORT:

1. This paper is to provide an update to the Committee on the Cultural Impact Assessment for the Ruataniwha Water Storage Feasibility Study and other communications

Background

2. The scope of the Cultural Impact Assessment (CIA), and consultants to be used were determined for the storage study in March 2010. The Eastern Institute of Technology (EIT) have been contracted to undertake this work which will be completed by Benita Wakefield. Roger Maaka and Morry Black have been mentoring Benita through this process. Roger is only able to assist in a mentoring capacity as he is a member of the Leadership team and further participation would be a conflict of interest. The EIT will handle the Information gathering stage of cultural assessment. The liaison phase will be handled by the External Relations group from HBRC.

3. The purpose of undertaking a cultural impact assessment (CIA) is to identify the potential benefits and issues for Tangata Whenua as a result of the proposed development. The CIA will provide technical information from a tikanga Maori perspective that will focus on: identifying any areas of cultural significance on specific sites of the proposed water irrigation scheme; a description of cultural values and traditional relationships with ancestral lands, water, sites, waahi tapu (sacred) and other taonga (treasures), that are associated with the Tukituki River (including tributaries, wetlands, beds and margins of the river). The CIA will also investigate any environmental issues of concern in terms of water flows, water quality, the effects of land use intensification and other issues.

4. A draft literature review has been written by the Benita from the EIT and supplied to Hawke’s Bay Regional Council. The purpose of this was to scope out cultural values of importance to the Tangata Whenua from the nine marae within the Ruataniwha region. The final version of the literature review will identify:

a) Site specific areas where the storage dams and irrigation zones are located to identify any waahi tapu (and other cultural values) areas of significance within the traditional boundaries of various Hapu/ Marae.

b) Assess the cumulative effects on the health state of the Tukituki and its tributaries within the Ruataniwha Takiwa/ District and the potential gains or detrimental impacts on Tangata Whenua cultural values and uses.

5. The hui for each potentially affected marae have been undertaken as well as a number of one on one interview’s and several site visits to potential water storage locations. Information packs about the project have been supplied to participants as well as a general overview of the project. Consent was gained to digitally record the session. The discussions were to involve the following:

a) Identifying and defining cultural values of importance to Tangata Whenua (i.e. tikanga, whakapapa, kaitiakitanga, mahinga kai, waahi tapu etc).

b) Identifying and defining social values of importance to Tangata Whenua.

c) Whanau perceptions of the potential cultural/ social and recreational gains.

d) Any cultural and social issues that are raised on the cumulative effects of the proposed storage dam scheme on the health of the Tukituki waterway and how their concerns might be resolved (or mitigated).

e) Feedback on site specific concerns and issues / or perceived gains for Maori.

6. A Leadership Group for the Ruataniwha Water Storage Feasibility Study was established to be the driving force behind the feasibility study. In particular, they will focus on the critical market, economic and financial issues for the project, establish relationships & link to investors, and ensure commercial viability. Dr Roger Maaka has been appointed as Iwi Advisor on the Leadership Group.

7. The Stakeholder group provides guidance to the Council on the fit of the project within the community - by assessing social, cultural, water use efficiency and environmental issues, opportunities and solutions. Liz Graham has been appointed as a Tamatea Taiwhenua representative.

8. A draft of the CIA is due early August, with the final due late August.

DECISION MAKING PROCESS:

Council is required to make a decision in accordance with Part 6 Sub-Part 1, of the Local Government Act 2002 (the Act). Staff have assessed the requirements contained within this section of the Act in relation to this item and have concluded that, as this report is for information only and no decision is to be made, the decision making provisions of the Local Government Act 2002 do not apply.

SUBJECT: High Flow Allocations

REASON FOR REPORT:

1. To provide scientific support for a high flow allocation methodology as part of the development of the Regional Resource Management Plan.

Background

2. Water allocation beyond core allocation blocks has progressed in several catchments in a fractioned, consent-driven manner due to the lack of policy guidance. This research aims to inform policy development for high flow allocation that addresses the cumulative effect of multiple water takes on river hydrology, ensuring that water is made available but without negative impact on flow variability.

Objective

3. The objective of this investigation was to model high flow allocation in the Ngaruroro River during the primary water harvesting months of June to November and to determine any effects on instream values. In conjunction with modelling, assessments were made on naturalised Ngaruroro river flows to determine if there was any negative effect on flushing flows, ecological flow requirements, and water quality flow requirements.

4. An idealised schematic of water allocation, including high flow allocation is presented to show the concept used in this investigation (Figure 1).

Figure 1. Idealised water allocation structure, showing core and high flow allocation blocks and provision for protecting environmental flows.

Methods

5. A review of reports on water quality and instream ecology was conducted to determine the potential effects of high flow allocation scenarios on those parameters.

6. Modelling of allocation scenarios began by developing a daily average naturalised flow record for the Ngaruroro River at the Fernhill Bridge hydrometric station. Eight high flow allocation scenarios were then constructed and applied to the naturalised flow record for comparison.

7. Comparative analysis was completed using the software package “Indicators of Hydraulic Alteration v7” developed by The Nature Conservancy. The IHA was used to quantify how each allocation scenario altered the frequency or duration of biologically significant flow events in the natural flow regime.

Summary and Conclusions

8. Eight high flow allocation methods have been modelled and investigated to determine a suitable method of allocating flow during times of higher river flow (June to November) which has minimal impact on the river ecology and hydrology.

9. Hydrological analyses showed small variations between the naturalised and altered Ngaruroro River flow for each high flow allocation method. Results of the ecological analyses recommend that in order to maintain instream ecological values, the mean FRE3 value for the Ngaruroro River should not be changed by more than 10% of its naturalised flow value. All eight high flow allocation methods investigated alter the FRE3 value by less than 10%.

10. Additional ecological analyses including water quality and temperature assessments, instream habitat, and fish passage concluded that there would be no significant effects from any of the high flow allocation methods.

11. As part of the IHA analysis, a Range of Variability Approach (RVA) analysis investigated the degree of hydrologic alteration between the naturalised flow (pre-impact) and altered flow (post-impact) for 32 hydrological parameters that statistically characterise ecologically significant features of the flow regime.

12. The RVA results showed that the four high flow allocation methods based on using the mean flow as the allocation threshold incurred the least hydrologic alteration on the Ngaruroro River flow.

13. Given the very similar results from the analyses for the eight methods and the only very minor effect they each have on the flow regime and instream ecology of the Ngaruroro River for the months of June to November, it comes down to a preference of what quantity of water should be made available for allocation. If the desire is to promote and encourage water harvesting for storage then Methods 2, 4, 6 and 8 would be preferable as they offer the greatest allocable volumes

14. The allocation scenarios investigated in this study have applied a flow share arrangement, for example, 50/50 - where 50% of the flow above a threshold is allocated up to a maximum allocation. This means that for every litre of water allocated a litre must stay in the river above the threshold. Consideration will need to be given to how this will be managed. Otago Regional Council found it a difficult proposition and instead nominated allocation blocks over and above certain threshold flows.

15. An example situation for the Ngaruroro River might be three allocations blocks:

a) A block – is the core allocation as defined by the minimum flow and the allocation limit

b) B block – the minimum flow for this would be the median/mean flow and an upper limit may be, for example, 3 m³/s above this, i.e. 3 m³/s available for allocation

c) C block – the minimum flow here could be the FRE3 value and an allocation limit could be, for example, 2 m³/s.

16. This effectively gives three allocation blocks with ‘gaps’ in between where flow is maintained. Allocation systems such as this are used in the Otago region. HBRC would need to ascertain whether the Ngaruroro River would require a similar system or if a straight flow sharing arrangement would work best.

Further Investigation

17. As an alternative to the recommended flow sharing allocation structure, block allocation is being modelled to determine the implications for water users and environmental flows.

18. High flow allocation scenarios (flow sharing and block) are also being modelled for the Tukituki catchment. Future modelling is tabled for other catchments including the Tutaekuri. This will allow the development of specific allocation structures which address the values of each catchment.

19. The modelling results for each allocation scenario will be put forward for consideration in the policy development process with recommendations for preferred scenarios. Recommended structures will allow optimisation of water allocation while still maintaining environmental flows.

20. Stakeholder consultation can then address each scenario in light of catchment-specific values before progressing to formation of high flow allocation policy in the Regional Resource Management Plan.

DECISION MAKING PROCESS:

21. Council is required to make a decision in accordance with Part 6 Sub-Part 1, of the Local Government Act 2002 (the Act). Staff have assessed the requirements contained within this section of the Act in relation to this item and have concluded that, as this report is for information only and no decision is to be made, the decision making provisions of the Local Government Act 2002 do not apply.

That the Maori Committee:

SUBJECT: Understanding Flow Patterns Within the Ruataniwha Basin

REASON FOR REPORT:

1. To gain an understanding of the physical hydrological system and to inform future water management decisions in the Ruataniwha Plains. This understanding is crucial for enabling an informed assessment of total water allocation and managing the river system.

Background

2. Previous concurrent gauging data for the Ruataniwha Plains have been recorded during 1973 and the summer of 1996/1997. These data were used historically to create maps of river flow patterns. Although of sufficient detail to provide insight into flow patterns, additional data were required to build statistical relationships and to investigate streams not previously studied.

3. The Ruataniwha Concurrent Gaugings Programme was developed to provide detailed hydrological data to inform review of current water allocation in the basin. The primary goals of this study were to describe in detail the gains and losses along streams in the Ruataniwha basin, establish flow correlations with recorder sites, and provide data for use in the Ruataniwha basin groundwater model. This will be used as an important component of establishing water allocation rules for both surface and groundwater in the Ruataniwha Basin.

4. Concurrent gaugings are stream flow measurements that are conducted at the same time at multiple points along a river system. Under steady state conditions, concurrent gaugings offer an instantaneous snapshot of the hydrology of a catchment. Over several repetitions, they can be used to form a picture of system-wide river flow patterns. If sufficient repetitions are completed, the data can be used to build statistical relationships between river segments and neighbouring catchments. This data can then be used to inform the water demand management process.

5. Consent conditions allow for temporary bans on consented water use for scientific investigations. Temporary bans to all consented water takes were issued before and during gauging runs to ensure that water abstraction did not affect river flows. Concurrent gauging runs were also conducted during fine weather to ensure rain pulses were not moving through the system.

Results

Surface Water Flow Patterns

6. Concurrent gaugings were conducted at 34 sites in the Ruataniwha Plains (Figure 1).

CCGG map

Figure 1: 2008/2009 concurrent gauging locations.

7. Drought conditions prevailed during the 2008/2009 summer over much of the Hawke’s Bay region. Zero flows were measured at certain locations in the Mangaonuku, Waipawa, and Tukituki rivers. Low flow patterns were able to be determined for all streams in the Ruataniwha Basin (Figure 2).

Figure 2: Surface water flow patterns from the 2008/2009 Concurrent Gauging Programme.

Mangaonuku

8. The Mangaonuku was gauged at three locations. Flow records indicate the Mangaonuku exhibits a strong baseflow over much of the hydrograph. Observations show that even at extreme low flows with no water in the upper river, groundwater gains sustain flow in the lower reaches. This is consistent with previous studies.

Waipawa

9. The Waipawa River was gauged at seven locations. The Waipawa experiences significant flow loss below SH 50. Loss from the river is believed to recharge the local groundwater system and then re-emerge as streamflow in tributary streams and the lower reach below the Mangaonuku confluence. The lower Waipawa above the Mangaonuku stream exhibits the most dramatic drying of the Ruataniwha rivers. During the concurrent gauging survey on 4 February 2009, the dry reach extended approximately 3.5 kilometres. A sharp increase in flow at SH2 is caused by flow from the Mangaonuku Stream, Cockrane’s Creek, and emergence of groundwater.

10. For the 2008/09 data, the sum of flows from the Waipawa and Makaroro above their confluence is approximately 5% less than the flow measured at Stewarts (below the confluence). This trend does not continue to SH50, which may indicate that there is an area of loss in the upper river that is not connected to the major loss area below SH50. Inspection of river profiles does not show any conspicuous gradient changes in the upper river which may influence this occurrence, so although there is a 5% difference, it is pragmatic to consider the reach above SH50 to be conservative flow, given the small magnitude of variation in the gauging data.

11. A gauging run conducted on 21 January 2009 measured the lowest flowing conditions in the lower river of 325 L/s. The concurrent flow at SH50 was 3865 L/s. A simple subtraction identifies the flow at which the lower river is expected to dry is 3545 L/s. This is confirmed using the correlation from all the concurrent data between the sites SH50 and End Plantation Road, which shows the Waipawa is likely to dry in the lower river when the flow at SH50 reaches 3500 L/s.

12. Flow patterns identified in the upper river during the 2008/09 gauging run appear to be different than during previous investigations. The majority of historical concurrent gaugings show loss in the upper river, but the 2008/09 series show slight gains on average (Table 1). It is important to note that the difference in flows is within gauging error (8%) for all but one gauging during the 2008/2009 run. Water take bans could influence a shift from small percentage loss to small percentage gain, but cannot reconcile the large losses seen in early data. It is unclear what has lead to this shift.

13. Previous studies also noted that flow loss is greater at high flows than at low flows. The 2008/2009 data do not show this trend.

Tukituki

14. The Tukituki was gauged at six locations in the Ruataniwha and two in the lower reaches. Flow loss was evident below SH50. As the Tukituki nears the eastern margin of the Ruataniwha basin, the Tukituki receives significant flow from the Kahahakuri and Tukipo. With the exception of one gauging pair, the sum of the Tukituki (below the Tukipo confluence) and Kahahakuri flows is within gauging error (8%) of the flow measured at Tapairu Road (Table 2). This indicates that little groundwater is gained between the Kahahakuri confluence and Tapairu Road.

15. The gauging run on 4 February 2009 measured near-zero flow in the Tukituki at Ongaonga-Waipukurau Road. The point at which flow ceased was also marked by GPS, approximately 2 kilometers from the Tukipo confluence. With this measurement it is possible to estimate the flow at which drying is likely to occur in the Tukituki. The zero flow at Ongaonga-Waipukurau Road corresponded to 1100 L/s at SH50, and is a good estimate for the point at which flow will cease in the Tukituki before it reaches the Tukipo confluence. The correlation using all data between Ongaonga-Waipukurau Road and SH50 indicates that drying will occur in the lower reaches when flow at SH50 is approximately 1200 L/s, which is in reasonable agreement with the flows observed on 4 February 2009.

Kahahakuri

16. The Kahahakuri Stream was gauged at two locations in the lower reach. The spring-fed nature of this stream is evident in both its physical character (narrow, meandering, incised channel with riparian growth to water’s edge and cool temperature) and the high baseflow hydrology. The Kahahakuri shows consistent flow patterns regardless of regional flows. Correlations are poor with other sites in the catchment; however a good flow record is available for this stream.

Tukipo

17. The Tukipo was gauged at five locations, with two additional gauging sites on its tributary, the Mangatewai Stream. The data show that the Tukipo consistently gains flow through its entire length. This is in contrast with previous runs that indicate there is a losing reach in the vicinity of Fairfield Road. It is important to consider that previous gauging studies did not enforce irrigation bans, so there is the possibility that those data are influenced by abstraction. The general gaining trend measured during the 2008/2009 study is consistent over all seven runs and is considered to be an accurate depiction of natural conditions and most useful for water resource analyses.

Makeretu, Porangahau, and Maharakeke

18. The Makeretu is the southernmost of the Ruataniwha streams that flow from the Ruahine Range. Three gauging locations were chosen on the Makeretu. The Porangahau is a tributary of the Maharakeke, which then enters the Makeretu at the end of its course. One gauging site was located on the Porangahau and two on the Maharakeke Stream.

19. Recent gauging data show the general trend in the Makeretu is slightly gaining above SH 50, and slightly losing below SH 50. It is important to note that the distances between gauging sites are substantial. Concurrent gaugings from 1996 and 1997 indicate that a short losing reach occurs approximately 7 kilometers from the Tukipo confluence. Along with the 1973 gaugings, they also indicate an overall gain in flow from Pagett’s Road to the Tukipo confluence, a trend not evident in the recent data. Further investigation will be required if it is to be determined that this change represents a long-term shift in flow patterns.

20. The Porangahau and Maharakeke data show a consistent gaining flow trend. The site at SH2 measures all flow in the Maharakeke and Porangahau Streams, which was compared to the sum of the two inflows to determine the percent change in flow. In this case, flows were consistently higher than the sum of both upstream sites indicating significant gaining conditions. The two gaugings upstream of the confluence have been compared to the downstream gauging at SH2 (Table 3). There is considerable distance between gauging sites but the magnitude of flow gain is high, indicating the source is groundwater discharge.

Lower Tukituki

21. Surface water flow patterns in the lower Tukituki River are less affected by groundwater discharge than in the Ruataniwha Plains. Aquifers in this area are thin, surficial river gravels of limited aerial extent and provide a negligible contribution to baseflow. Concurrent gauging data are available for the sites Shagrock, Patangata, and Red Bridge. Shagrock and Patangata are located downstream of the confluence of the Waipawa and Tukituki Rivers, which allows for measurement of all flow exiting the Ruataniwha basin. Red Bridge is located approximately 14 kilometers from the Tukituki river mouth and is used as a gauge for the total amount of water exiting the system. The data for these sites indicate an average flow increase of 5%. There are no concurrent gauging data for the lower tributary catchments, so definite figures of tributary inflow cannot be calculated. These catchments have limited water resources and were not included in the concurrent gauging programme. However, estimates of flow based on isolated gaugings indicate that tributaries account for all of the increase measured at Red Bridge.

Conclusion and Further Work

22. A detailed assessment of gain and loss from rivers has been mapped in the Ruataniwha Basin. The flow patterns discerned from these data corroborate major historical patterns; loss in the mid-reaches of the Waipawa and Tukituki Rivers and significant gains in the Mangaonuku and Kahahakuri Streams.

23. Changes from historical flow patterns have also been observed. The Tukituki River below the Kahahakuri confluence was measured as stable (no major gain or loss), where historical data show gaining conditions. Stable flow was also measured in the upper Waipawa and Tukituki rivers, which were previously observed as losing reaches

24. Additional field work will be required to confirm if the changes observed during the Concurrent Gauging Program represent a shift in long-term flow patterns.

25. The data from the Concurrent Gauging Program were incorporated in the Ruataniwha Transient Groundwater Model and aided in its successful development.

26. Correlations between sites have been drawn which aid in calculating flow statistics (like the mean annual low flow) for a number of sites with poor flow records.

27. Concurrent data in the absence of abstraction have shown an accurate depiction of the total contribution of streamflow from each tributary catchment. This will be used to inform the distribution of water allocation (core, high flow, and dam-fill) throughout the Ruataniwha Basin.

28. This information will be used to inform policy development which will address equitable distribution of water allocation in the Ruataniwha Basin.

SUBJECT: Low Flow Monitoring Report 2008-2009

REASON FOR REPORT:

1. This paper provides a summary of the Low Flow Monitoring Report 2008-2009 and the low flow monitoring undertaken during 2009-2010 summer.

2. The executive summary of the report “Low Flow Monitoring Report 2008-2009” is included as Attachment 1.

Background

3. Minimum flows have been established on rivers and streams via Policy 74, Table 9 of the RRMP. Minimum flows are set to ensure sufficient water is left in a river to help maintain identified river values.

4. Minimum flows are set for specific points (known as minimum flow sites or low flow sites) on rivers where the flow can be monitored.

5. Some rivers/streams have additional abstraction cut-off levels set at flow levels above the minimum flow that relate to high flow allocation consents. All minimum flows and additional cut-off levels are commonly referred to as low flow limits.

6. Rivers may naturally reach minimum flow conditions over extended dry periods. Abstraction however can speed up the recession of the river and extend ban periods. Measuring ban days is particularly important for enabling water users to assess the security of water supply. In turn water users may implement measures to mitigate interruption of supply such as storage, developing water efficient practices and rationing/rostering which will help reduce exposure to abstraction bans.

The Low Flow Monitoring Programme

7. River flows are continuously monitored throughout the year by the HBRC hydrology team. Low flow conditions typically occur during (although not confined to) the summer months (November-April) when the region regularly experiences dry periods with low rainfall and river flows. This is characteristic of the east coast of both the north and south islands.

8. River flows at low flow sites across the region, are assessed on a daily basis. When a river flow is measured nearing its low flow limit, the HBRC communicates to relevant consent holders that a low flow ban is approaching. If conditions persist and the river recession continues, reaching its low flow limit or below, the HBRC issues an abstraction ban notifying the relevant consent holders to cease abstraction. When river flows recover above the low flow limit, the HBRC will cancel the abstraction ban notifying all related consent holders.

9. A low flow assessment meeting is held weekly to assess current and predicted river flows, abstraction bans and forecasted weather. Changes to abstraction bans are communicated to the relevant consent holders via email, fax, or phone. River flows constantly fluctuate, and the daily assessment of river flows means abstraction bans can also change on a daily basis. Abstraction bans and related river flows are also presented on the HBRC Low Flows web page. This web page is updated as the situation changes.

10. Abstraction bans have been recorded since 1994. These records detail the start and end of every abstraction ban for all minimum flows at all sites. From these records, the number of ban days has been calculated for each ban.

11. Thirty low flow sites across Hawke’s Bay were monitored during 2008-2009 and again in 2009-2010. Maps of these sites are included in Attachment 2 (2008-2009) and Attachment 3 (2009-2010).

Low Flow Monitoring Report

12. Low flows are reported:

a) Weekly (as a result of the weekly assessment meeting) on the HBRC Low Flows web page at www.hbrc.govt.nz

b) Daily (only when changes to abstractions bans are required between weekly assessment meetings) on the HBRC Low Flows web page at www.hbrc.govt.nz

c) Monthly on the HBRC Low Flows web page at www.hbrc.govt.nz

d) Annually in an HBRC technical report (executive summary for 2008-2009 report included as Attachment 1).

13. In addition, media releases are issued several times each summer as conditions develop.

14. For the 2008-2009 low flow monitoring season, the following statistics are detailed in the report:

a) The 2008-2009 low flow season started in November 2008 with the last ban ending in July 2009, spanning a total of 227 days

b) Rivers and streams were placed on ban for a combined total of 1926 days

c) The Karewarewa Stream in the Karamu catchment was on ban for the greatest number of days, totalling 224

d) February 2009 had the highest number of total ban days (417) and also the greatest number of low flow sites on ban (21 of a total of 30)

e) Graphs showing abstraction ban days per low flow site and abstraction ban days per month for 2008-2009 are included as Attachment 2

f) Report recommendations are made to ensure that the low flow monitoring programme continues to develop and adapts to changes in consenting processes and increasing water resource pressures.

15. Statistics for the 2009-2010 low flow monitoring season are also identified below. The 2009-2010 report will be completed by August this year:

a) The 2009-2010 low flow season started in November 2009 with the last ban ending in May 2010, spanning a total of 180 days

b) Rivers and streams were placed on ban for a combined total of 1142 days

c) The Karewarewa Stream in the Karamu catchment was on ban for the greatest number of days, totalling 117

d) April 20010 had the highest number of total ban days (366)

e) May 2010 had the greatest number of low flow sites on ban (18)

f) Graphs showing abstraction ban days per low flow site and abstraction ban days per month for 2009-2010 are included as Attachment 3.

Comparison to Previous Years

16. The following graph compares the number of ban days for low flow limits at five sites over previous low flow seasons. River flows and rainfall across the region have regularly been below normal during the summer months (Nov-Apr) over recent years, with the exception of 2005/2006 summer. The number and length of abstractions bans during each summer is ultimately dependant on the climate and state of the river flows. The number of ban days for most of the sites in the graph below, show peaks in ban days during the 2007/2008 and 2008-2009 seasons, which corresponds with well below normal river flows experienced during these seasons.

17. Rainfall and river flow conditions also vary between catchments and coupled with different resource pressures, there are always variations in the time and duration of abstraction bans between catchments, shown in the graph by the differing numbers of ban days between sites for the same season.

18. This report records the general ban day statistics in rivers and streams around the region over the last few years.

19. Underlying these statistics is the critical importance to arrive at a robust balance of competing users and uses (environmental, economic, social and cultural). Further, this information will play a critical part in guiding other interventions to increase security of supply, such as irrigation storage infrastructure.

DECISION MAKING PROCESS:

20. Council is required to make a decision in accordance with Part 6 Sub-Part 1, of the Local Government Act 2002 (the Act). Staff have assessed the requirements contained within this section of the Act in relation to this item and have concluded that, as this report is for information only and no decision is to be made, the decision making provisions of the Local Government Act 2002 do not apply.

SUBJECT: Ruataniwha Basin Transient Groundwater-Surface Water Flow Model

REASON FOR REPORT:

1. This paper provides a summary of the development and results of the Ruataniwha groundwater model project.

2. A short presentation on the paper will be provided to the Committee bgy Husam Baalousha – Senior Groundwater Scientist.

Background

3. The Ruataniwha groundwater resource is found in gravels and minor volcanic ash within a fault bounded basin between the Ruahine ranges to the west and the towns of Waipawa and Waipakurau. The gravels were washed into the basin in the last 2 million years from rivers draining the Ruahine ranges.

4. Two main water bearing formations, young gravels and the older Salisbury gravels form the groundwater system in the basin which cover an area of 806 km² and extend to a maximum depth of 200m in the centre of the basin. The gravels are discontinuously layered with clay to form a series of interlinked aquifers.

5. Four major rivers and their tributaries drain the Ruahine Ranges and flow across the plains. Previous studies of river and stream flow gauging in the basin together with hydraulic testing of the aquifers have shown that the groundwater system in the basin is inextricably linked to the overlying rivers and streams in the basin. Essentially the basin is “closed” with inflow to the basin derived from rainfall runoff from the hard rock Ruahine ranges to the west and from rainfall that falls directly in the basin.

6. The total land area under irrigation in the Ruataniwha Plans has increased from 2200 hectares in 1995 to approximately 7000 hectares at present. Councils’ consents section is experiencing increasing demand for new takes in the basin as there is up to 32,000 hectares of available land on the plains.

7. There has also been considerable land use intensification in the last 10 years resulting in a change in water use from 1.2 million cubic metres to over 20 million cubic metres per year. The plains are prone to annual summer droughts so any future land use development is likely to be dependent on irrigation.

8. Surface water resources in the basin are already fully allocated under Council’s existing Regional Resource Management Plan and water users have looked to groundwater as an alternative supply. The effects of groundwater abstraction are now being expressed as declines in aquifer levels in parts of the basin.

9. Understanding the groundwater flow systems, interaction between surface and groundwater, potential effects of further groundwater abstraction on security of supply of existing water users and wider environmental effects are key issues that need to be investigated to enable sustainable management of the water resources in the basin.

10. Therefore a groundwater modelling tool was developed to help address these issues. The model is on a basin wide scale and brings together all available information for the groundwater system in the basin using up-to-date computational software to simulate groundwater/surface water flow in the basin.

Model Development

11. The model was developed in three main stages; water balance assessment and conceptualisation, steady state and finally transient. The water balance considers the main inflows or recharge to the aquifer systems. Conceptualisation of the aquifer system is based on geological and hydraulic properties of the aquifer system.

12. Three main layers were used to conceptualised or represent the basin groundwater system in the model. A shallow confined/unconfined layer at the top comprising of relatively young gravels, a clay layer (aquatard) that separates a deeper and older Salisbury gravel aquifer formation. The model software uses a finite difference grid cell structure with the groundwater system represented in a series of columns and rows. In this model there are a total of 8051 cells in each layer.

13. Available information for the groundwater system such as aquifer hydraulic properties, recharge and historic water level data, were brought into model and then optimised and calibrated to a steady state condition. The steady state model is the pre-development condition which is assumed to be pre-1990 basin conditions based on available historical allocation information and local knowledge.

14. The transient model was then developed to take account of climatic and abstraction changes through time. Review of groundwater compliance data showed that annual groundwater abstraction has increased from 3 million cubic metres in 1990 (assumed steady state) to 24 million cubic metres in 2009 as shown in figure 1. However the actual abstraction was found to be only 30% of the consented allocation.

Figure 1 Annual groundwater abstraction change from 1990 to 2010.

15. The transient model includes the summer/winter variations in groundwater abstraction, and also considered climatic variations in recharge and stream flow, strong interaction between the groundwater system and rivers, and streams that flow across the basin.

16. The model was calibrated using the monitoring results of water level data from the State of Environment monitoring network and water level survey information. The calibrated model shows a good match between measured and simulated head at the SOE wells.

Model Results

17. The model shows that the groundwater flow is essentially from north-west to south-east direction. At depth, groundwater flow is horizontal at the western boundary of the basin, downward movement in the centre of the basin and upward groundwater movement at the eastern exit point of the basin near the confluence of the Waipawa and the Tukituki rivers. Groundwater flow speed increases travelling down the basin to reach the maximum speed at the basin exit point as shown in figure 2.

head_transient.tif

Figure 2. Simulated groundwater head and flow direction. The red colour means upward groundwater movement, the yellow colour means downward gradient and the blue means horizontal flow. Length of arrow is indicative of groundwater speed.

18. Rivers and streams in the basin were found to be generally gaining water from the groundwater system. The amount of gain increases with river flow down the basin. Water budget results show that the average annual groundwater recharge is approximately 256 million m³ which is almost equal to rivers gain from aquifers.

19. The transient water balance indicates that stream gain and rainfall recharge are the largest components in the water budget and that total stream gain and springs flow is approximately equal to rainfall recharge. Well abstraction constitutes only 3.4% of the total budget but storage losses constitute approximately 6.0% of the water budget. Even though groundwater abstraction is low compared to recharge, abstraction has resulted in a loss of 66 million cubic metres from storage since 1990.

20. The loss of storage is already impacting on spring and river flows. The model water balance results indicate a decreasing trend in spring flow (Figure 3) and a measurable decrease in the average summer flow in Tukituiki River from 2007 to 2009 (figure 4), that is independent of current climate variation. Predicted river flow simulations closely follow measured changes which gives a high degree of confidence in the ability of the model to provide defensible predictions for any future water management scenarios.

Figure 4. Simulated and measured flow at lower end of the Tukituki River.

21. The model will now be used to run a series of allocation scenarios to inform allocation policy development for the groundwater resource in the basin. A number of scenarios that have been developed in consultation with staff from the planning, consents and water initiatives team. These scenarios include full uptake of existing consented allocation, increases in irrigation land to 14,000 hectares, and scenarios that reflect the Ministry for the Environment Low Flow Guidelines.

22. Results from the model will be communicated to key stakeholders in Ruataniwha community and water users groups through a series of seminars and workshops.

DECISION MAKING PROCESS:

23. Council is required to make a decision in accordance with Part 6 Sub-Part 1, of the Local Government Act 2002 (the Act). Staff have assessed the requirements contained within this section of the Act in relation to this item and have concluded that, as this report is for information only and no decision is to be made, the decision making provisions of the Local Government Act 2002 do not apply.
