  1. San Joaquin River Restoration Program Water Management Goal Stakeholder Coordination Meeting July 11, 2008

  2. Agenda • Introductions / Purpose of Meeting • Overview of Initial Water Management Alternatives • Recapture Opportunities • Surplus Water / RWA Supply Opportunities • Next Steps

  3. Overview of Initial Program Alternatives Report(IPAR)

  4. Two Goals of the Settlement • Restoration Goal - To restore and maintain fish populations in “good condition” in the main stem of the San Joaquin River below Friant Dam to the confluence of the Merced River, including naturally reproducing and self-sustaining populations of salmon and other fish. • Water Management Goal - To reduce or avoid adverse water supply impacts to all of the Friant Division long-term contractors that may result from the Interim Flows and Restoration Flows provided for in the Settlement.

  5. Program Document Emphasis Preferred Program Alternative

  6. Are Not Complete alternatives Site specific Likely to pass to PEIS Are Separate restoration & WM Program level of detail Starting point for evaluation Initial Program Alternatives The IPAR presents: • 8 Restoration Initial Alternatives • 8 Water Management Initial Alternatives

  7. Initial Water Management Alternatives

  8. Water Management Provisions of the Settlement Guided Initial Alternatives • Paragraph 16a: Develop and implement a plan to recirculate, recapture, reuse, exchange or transfer Interim and Restoration flows to reduce water supply impacts to Friant Districts • Paragraph 16b: Implement a Recovered Water Account that will make wet year water at Friant Dam available to impacted long-term Friant water users at $10/af

  9. Water Management Options Were Compiled from Several Sources • Senator Feinstein Report • Individual district projects • Integrated Regional Water Management Plans • Water Supply Study • Meetings with Friant Division districts • Total of 77 water management options • Regional conveyance • Local conveyance and storage

  10. Regional Conveyance Options Were Grouped by Source • 16a Regional Conveyance Facilities • Existing: Jones/Banks pumping plants • Existing: Exchanges on San Joaquin River with • Patterson WD • Banta-Carbona ID • West Stanislaus ID • Exchange Contractors • New: Pump-back on FKC • New: San Joaquin River pumps • 16b Regional Conveyance Facilities • Existing: FKC & MC existing capacity • New: Corrected/Upgraded FKC & MC capacity

  11. Local Conveyance & Storage Options Can Support One or Both Sources • 16a Local Conveyance (east-west) • Existing: Cross Valley Canal (including expansion), AEWSD Intertie, Semitropic/SWID • New: Trans Valley Canal (3 alignments), Mid-Valley Canal, TLBWSD Exchange, Kings River pump-in • 16a/16b Local Storage • Existing & New: Direct and in-lieu groundwater storage, surface storage • Other Suggested Options • Conservation & efficiency projects • Transfers/exchanges • Non-Settlement water sources

  12. Access 16a and 16b supplies Include Existing and expanded regional conveyance Include Existing and expanded local conveyance and storage 16a 16b Initial Water Management Alternatives Facilities in Initial Alternatives

  13. Initial Water Management Alternatives are a Mix of Regional and Local Projects

  14. Paragraph 16aRecapture Opportunities

  15. Recapture Opportunities • Possible Locations • Delta Pumping Facilities • Lower San Joaquin River pumping plant • Recapture Methods • Direct Diversion to DMC and CA • Exchange River Flows with CVP Water Users • Constraints • Delta pumping restrictions • DMC/CA available capacity • Exchangeable demand on San Joaquin River • Water quality

  16. Water Recapture Opportunities Using Delta Pumping Facilities (TAF/yr)

  17. Riparian water right holders with CVP contracts Diversion and in-district facility changes may be needed Additional coordination is needed to assess feasibility Exchange Opportunities for Water Recapture on the Lower SJR

  18. Opportunities for SJR Recapture is Affected by Water Quality Patterson Location Water quality significantly limits recapture opportunity at Patterson Vernalis Location Water quality is less constraining at Vernalis, but still limits recapture opportunities

  19. Potential for recapture from the Lower San Joaquin River depends on pumping capacity

  20. Paragraph 16bRecovered Water Account Supplies

  21. Evaluation of 16B Supplies Must Consider Several Areas of Uncertainty • Friant districts may operate differently under settlement conditions • Storage and/or conveyance will determine the size and location of 16(b) opportunities • Capacity & location of future banking facilities

  22. Approach to Estimating 16b Opportunities • Identify canal capacity by reach • Design, physical, operational • Review historical daily data • Identify availability of historic surplus supplies (flood releases) • Compare water availability canal capacity • Perform long-term hydrologic model simulations • Represent canal reach restrictions and deliveries

  23. Identify physical capacity in each canal reach • Designed neck downs • Known choke points

  24. Existing Friant-Kern Canal Capacity

  25. Existing Madera Canal Capacity

  26. Review of Historical Canal Operations

  27. Availability of Additional Water • Historical daily operations of Friant Dam • 1976-2008 • Friant Dam operating parameters • Reclamation data

  28. Historical Canal Utilization • Historical daily operations of Friant-Kern and Madera Canals at Friant Dam • 1976-2008 • Reclamation data • Historical daily operations of Friant-Kern canal • 2001-2006 • Friant Water Users Authority data

  29. Opportunities Occur when Water and Canal Capacity are Available Available water Opportunities? Available capacity

  30. Opportunities at Friant-Kern Canal Head • Friant-Kern Headworks • Diversions (black line) v. Capacity (red dash) • Total Releases (blue area)

  31. Opportunities at Madera Canal Head

  32. Opportunities along the Friant-Kern Canal

  33. Testable uncertainties Capacity constraints Storage opportunities Remaining Uncertainties Changes in use of Class-1 and -2 supplies Changes in value of water supplies … guidance is needed for considering the above uncertainties within the long-term analysis Uncertainty

  34. Status • Historical data evaluation • Detailed results will be available soon • Long-term monthly modeling • Will be based on Restoration Releases • Will account for Tulare Basin tributary surplus • Ideally should include information on changes in district operations under Settlement – but how?

  35. Next Steps

  36. Program Document Emphasis Preferred Program Alternative

  37. Criteria for Evaluating Initial Alternatives • Cost • Likelihood for Restoration and Water Management Success • Compatibility with other goal • Flexibility under variable conditions and outcomes • Implementation requirements and timeframe • Environmental acceptability / tradeoffs • Timing • Other …

  38. Upcoming Milestones Program Alternatives Report – Oct 2008 • Reduce number of alternatives for analysis in PEIS/R • Combine Restoration and Water Management Alternatives Draft PEIS/R – March 2009 • Incorporate Restoration/Water Management alternatives into CALSIM • Perform system-wide evaluation of Restoration/Water Management Alternatives

  39. Next Meetings… Water Management Goal • August 8th, 11-1, Visalia • Mid-September, TBD
