  1. BDCP Update May 26 -- 27, 2010

  2. Where are we today? Pelagic Organism Decline ESA lawsuits re: delta smelt and salmon Additional species candidates for listing Green Sturgeon Longfin smelt Drought

  3. How Water Currently Flows Across the Delta 3 Sac River Reverses SanJoaquin River 2 SWP Pumps CVP Pumps Sac River– Delta Cross Channel– Mokelumne River– Old & Middle Rivers 1 Ocean/TidalHigh salinity South Delta River Reversals

  4. What is the BDCP? Multiple species, contribute to long-recovery Conservation Plan Conservation Strategy Aspects of implementation + + + = ESA - HCP NCCPA - NCCP

  5. Covered Species • Delta smelt • Longfin smelt • Chinook Salmon • winter, spring, fall and late fall • Green and white sturgeon • Central valley steelhead • Sacramento splittail • 48 terrestrial species (Giant garter snake, Swainson’s hawk, Burrowing owl, others)

  6. Aquatic Conservation Measures Biological Goals & Objectives For Covered Fish Species Improve survival Improve fitness Improve distribution Improve growth rate Decrease mortality Habitat Restoration Conservation Actions Phytoplankton and zooplankton (fish food) Spawning and rearing Other Stressors Conservation Actions Reduce contaminants Reduce predation effects Improve fish passage Reduce Disease Reduce non-natives Water Operations Conservation Actions Improve water quality Reduce entrainment Improve water flow and habitat conditions

  7. Dual Conveyance Flow and Habitat Fundamentals East/west flow pattern Habitat interaction Water reliability and quality 1 2 3 SWP Pumps CVP Pumps Ocean/TidalHigh salinity

  8. Draft Conservation Strategy – Major Elements • Other Stressors • Reduce methylmercury • Remove non-native aquatic plants • Reduce illegal harvest • Establish hatchery and genetic management plans • Support Delta and longfin smelt propagation programs • Reduce predators • Construct non-physical barriers to re-direct juvenile salmonids • Water Facilities & • Operations • North Delta diversion • 5 intakes • 15,000 cfs design capacity • Tunnel/Pipeline subject of focused study in BDCP • Minimum flows to ensure healthy habitat and water quality • Sacramento River flows are always greater than exports • Two-Gates Facilities Habitat Restoration • Up to 80,000 acres tidal marsh, riparian, and floodplain • Enhanced floodplain in the Yolo Bypass-temporary inundation • 20-40 linear miles channel restoration • Approx. 45,000 acres of terrestrial habitat (grasslands, etc) for additional plant & wildlife species needs

  9. Draft Conversation Strategy - Flows

  10. Potential Habitat Restoration Potential Tunnel Conveyance

  11. Terrestrial Natural Communities & Species • 48 Species for Coverage • Total Terrestrial Restoration Target approx 101,000 – 115,000 acres • 70,000 acres tidal marsh/riparian restoration for aquatic species also supports 28 terrestrial species • Propose additional approx 45,000 acres. • Natural Communities • Vernal Pool – 500 acres • Non-Tidal Aquatic and Wetland – 400 acres • Agricultural Habitat Landscapes – 16,000-33,000 acres • Grasslands and Associated Wetlands (eg Alkali Seasonal, Vernal Pool) -16,000 acres

  12. Key Issues • Ongoing analysis to determine effects of plan on fish and wildlife species • Refine/determine proposed conservation measures. • Determine design aspects of a tunnel/pipeline • Sizing • Refine initial approaches to habitat restoration • Compatibility with existing and planned future land uses; integrating with other Delta conservation efforts • Determine what gets implemented when during 50-year planning horizon • Cost and financing of conveyance, habitat restoration, and other stressor measures • Governance structure

  13. Public Input • Delta Community Workshops Held in 2009 • Technical focus on draft conservation strategy • Ongoing Steering Committee Meetings- Open to the Public • Ongoing and Future Stakeholder Briefings • Local jurisdictions • Recreational interests • Water users • Agriculture • Tribes • Environmental Justice communities • Public Draft Conservation Plan - Public Draft EIR/EIS – Early 2011
