Overview of Initial Program Alternatives
Report(IPAR)

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.

Initial Program Alternatives

• Are Not
• Complete alternatives
• Site specific
• Likely to pass to PEIS

• Are
• Separate restoration WM
• Program level of detail
• Starting point for evaluation

• The IPAR presents
• 8 Restoration Initial Alternatives
• 8 Water Management Initial Alternatives

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
Initial Water Management Alternatives

• Access 16a and 16b supplies
• Include Existing and expanded regional conveyance
• Include Existing and expanded local conveyance
  and storage

Facilities in Initial Alternatives

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
Exchange Opportunities for Water Recapture on the
Lower SJR

• Riparian water right holders with CVP contracts
• Diversion and in-district facility changes may be
  needed
• Additional coordination is needed to assess
  feasibility

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

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
Uncertainty

• 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

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?

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
Program Alternatives Report Oct 2008
Upcoming Milestones

• 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
