CVP Operations Criteria and Plan and CVP/SWP OCAP Biological Assessment November 16, 2004
CVP Operations Criteria and Plan and CVP/SWP OCAP Biological Assessment November 16, 2004 Purpose & Objectives • Explain the relationship of the OCAP, BA, BOs • Explain some overall comparisons in the OCAP • Explain CVP/SWP current and future operations • Explain contents of the BA Operations Criteria and Plan (OCAP) Purpose • Documents CVP operations • Provides basis for BA project description – Developed in 1992 for the winter-run Chinook salmon BA • Documents changes since 1992 OCAP Document • Not a NEPA/CEQA decision document • Provides detailed project description of CVP/SWP • Explains regulatory and legal requirements • Includes project operations constraints and objectives • Presents modeling changes (1991 to present) • Explains forecasting process OCAP Outline • Introduction • Project-Wide Operations Constraints and Objectives • CVP Division Operations Constraints and Objectives • State Water Projects • Last few chapters on Modeling and Results Modeling for OCAP (2001 LOD) Article 21 Refuge Deliveries Trinity Required Flows D1485 WinterRun B.O. 95 WQCP D1641 Study A D1485 (1991) Historical Level 2 340,000 af/yr X Study B D1485 (1992) Firm Level 2 Same as above X Study C D1485 (1993) Same as above Same as above X Study D WQCP (1994) Same as above Same as above X X CVPIA 3406 (b)(2) EWA X Study 1 WQCP (1997) X Same as above Same as above X X X Study 3 Today EWA (2004) X Same as above 369,000453,000 af/yr X X X X Shasta end of May Storage May 5000 4500 4000 Shasta Storage (TAF 3500 3000 2500 2000 1500 1000 D1485 (1991) D1485 (1992) D1485 (1993) D1641 (1994) D1641(1997) Today EWA 500 0 0% 10% 20% 30% 40% 50% 60% Probability of Exceedence 70% 80% 90% 100% Shasta Storage Chronology 1928-1934 Shasta 5000 4500 4000 Storage (TAF) 3500 3000 2500 2000 1500 1000 500 0 Oct-27 Mar-29 Jul-30 D1485 (1991) D1485 (1992) D1641(1997) Today EWA Dec-31 D1485 (1993) Apr-33 D1641 (1994) Sep-34 Folsom end of May Storage May 1000 900 800 Folsom Storage (TAF 700 600 500 400 300 200 100 0 0% 10% 20% 30% 40% 50% 60% Probability of Exceedence D1485 (1991) D1641 (1994) D1485 (1992) D1641(1997) 70% 80% D1485 (1993) Today EWA 90% 100% Folsom Storage Chronology 1928-1934 Folsom 1200 1932 Wet Year on American River Reservoir was able to refill 1000 Storage (TAF) 800 600 400 200 0 Oct-27 Mar-29 Jul-30 Dec-31 Apr-33 D1485 (1991) D1485 (1992) D1485 (1993) D1641 (1994) D1641(1997) Today EWA Sep-34 Total Annual Delta Outflow 30000 Annual Outflow 25000 20000 15000 10000 5000 0 Average Wet Above Normal Below Normal Dry Critical Water Year Type D1485 (1991) D1485 (1992) D1485 (1993) D1641 (1994) D1641(1997) Today EWA Total Annual Outflow Dry and Critical Years 11000 10000 D1485 (1991) D1485 (1992) D1485 (1993) D1641 (1994) D1641(1997) Today EWA Total Annual Outflow (TAF 9000 8000 7000 6000 5000 4000 3000 2000 D D D D D D D D D D D D D D D D C C Water Year Type (Wetter --> Drier) C C C C C C C C C Total Annual Federal Pumping 4000 Annual Federal Pumping (TAF 3500 3000 2500 2000 1500 1000 500 0 0.0% 10.0% 20.0% 30.0% 40.0% 50.0% 60.0% 70.0% 80.0% Exceedance Probability D1485 (1991) D1641 (1994) D1485 (1992) D1641(1997) D1485 (1993) Today EWA 90.0% 100.0% South of the Delta Agriculture Allocation NOD AG 100% 90% 80% Allocation (% 70% 60% 50% 40% D1485 (1991) D1485 (1992) D1485 (1993) 30% D1641 (1994) D1641(1997) Today EWA 20% 10% 0% 0% 10% 20% 30% 40% 50% 60% Probability of Exceedence 70% 80% 90% 100% South of the Delta M&I Delivery SOD MI 100% 90% 80% Allocation (% 70% 60% 50% 40% 30% D1485 (1991) D1485 (1992) D1485 (1993) D1641 (1994) D1641(1997) Today EWA 20% 10% 0% 0% 10% 20% 30% 40% 50% 60% Probability of Exceedence 70% 80% 90% 100% Biological Assessment • Consultation information document • Not a NEPA/CEQA decision document • Identification of existing and potential actions • Analyses of effects on listed species from CVP/SWP operations ESA Consultation • Section 7(a)(2) consultation with FWS & NOAA Fisheries • Addresses combined major hydrologic operations of the CVP/SWP • Reclamation lead Federal agency • DWR lead State agency History of Key Listings • Winter-run Chinook Salmon – NOAA Fisheries listed as threatened in 1990, endangered in 1994 • Delta Smelt – FWS listed as threatened 1993 • Coho Salmon (in the Trinity River) – NOAA Fisheries listed as threatened in 1997 • Steelhead – NOAA Fisheries listed as threatened in 1998 • Spring-run Chinook Salmon – NOAA Fisheries listed as threatened in 1999 Reason for Consultation • CVP/SWP operations affect listed species – Primarily coho salmon, winter-run and spring-run Chinook salmon, steelhead, and Delta smelt • Long-Term BOs date from 1993 & 1995 • Interim BO on spring-run/steelhead Why Update Now?
