    1. Agricultural Water Management Issues for 2000 and Beyond Jerry Johns Division Of Water Rights State Water Resources Control Board

    2. Agricultural Water Management Issues for 2000 and Beyond Water Transfers and Agriculture Increasing Water Demand Pressures Total Maximum Daily Loads CWA Threats to Beneficial Uses ESA and Public Trust on Water Supplies Coexistence with Environmental Protection

    3. Water Transfers and Water Supply Development Analogy with Housing Housing Issues - Water Supply New House - New Dams Remodel - Conservation/Transfers Garage Sale - Not with Water Water is a usufructuary right If you are not using it - somebody is Changes to Water Rights - “No Injury” Rule

    4. Effective Water Management Can Make Water Available Expanded Agricultural Uses in Same Area Drip Irrigation and Vineyards Water to Water Short Neighbors SJR Exchange to Westlands Water Transfers to Other Uses IID to MWD and San Diego

    5. Four General Rules Related to Water Transfers Rights to the Water Must Exist Stay with the water right holder not those receiving the water transfer “No loss of water rights” at least 8 different water code sections “No Injury” to legal users of water “No unreasonable effects” on fish and wildlife

    6. Water Conservation and Water Transfers (1010 &1011) Rights to conserved water not lost Water conservation defined as “less water to accomplish the same purpose of use” Water saved due to “water conservation efforts” is transferable Transferable “pursuant any provision of law relating to the transfer of water” File reports with SWRCB to get the benefits of the section

    7. No Injury Rule No injury to other legal users of water Not just prior users - any other user Protects juniors from seniors Based in old court cases, now in statute Applies to both pre and post 1914 rights (1706, 1702, 1727, 1736) What’s injury - Imported water/ watershed protection

    8. Agricultural Water Use Without water conservation

    9. Agricultural Water Use With water conservation (No change in consumptive use)

    10. Agricultural Water Use With water conservation (With change in consumptive use)

    11. Observations on Transfers Transfers are the future Not the panacea but a useful tool Processing short-term transfers is our highest priority Instream flow transfers will require special tracking through the Delta Follow the water not the trades

    12. Some Outstanding Issues with Water Transfers Capacity across the Delta Groundwater storage and extraction of transfers Instream flow transfers - Environmental Water Account (EWA) Pre-1914 Transfers Water Transfer Clearinghouse

    13. Total Maximum Daily Loads Required by CWA for Impaired Water Bodies (those not meeting WQ Stds.) 1472 TMDLs to be done Half in the Los Angles Region Most are Non-Point Source Related In Central Valley almost half are Agriculture Related Pesticides, Nutrients, Toxicity, Salinity

    14. TMDL Process for CWA Identify Levels of Exceedance Identify Sources Determine TMDL to achieve Standards

    15. TMDL Implementation By the State Non-Point Source will look more like BMP Agriculture needs to work with the Regional Board Source Identification Methods of load reduction (BMP’s) Rice Herbicides Selenium

    16. State and Federal Endangered Species Acts and Public Trust Public Trust - 1983 Supreme Court Decision Related to Mono Lake SWRCB water Right Decision 1631 in 1994 reduced LADWP exports by about half Being used in other areas to address past problems SWRCB Continued Supervision Responsibility of Public Trust Resources Two Edged Sword - Balancing

    17. State and Federal ESA Consultation Process for Federal Agency Projects Redress for Past Actions “Take” Prohibitions Aggressive Implementation in the 1990’s Winter Run, Delta Smelt, Spring Run Impacts on Water Supplies Continued Consultation Central Valley,Russian, Cachuma

    18. Implications for the Future Recognize past reductions in natural resources caused by Water Projects Become involved in recovery efforts Pacific Flyway recovery Seek Financial Assistance Fish Screening, Spawning Habitat, Migration Barriers, Flows

    19. Implications for the Future Cont. Build on Areas of Success Temperature Control Devices Spring Run in Sacramento Valley Hilton Creek - Cachuma Innovative Solution Mendocino Dam Bypass Fish Migration Gravels Stewardship - Strive for Balanced Solution
