1. Irrigation Mobile Lab Yolo, Solano, & Colusa County Resource Conservation Districts The Yolo Resource Conservation District (RCD) is a farmer-led special district working with the USDA Natural Resources Conservation Service (NRCS) to support local landowners’ efforts to sustain local agricultural & natural resources. The Yolo RCD promotes stewardship by demonstrating conservation practices through cooperative land users, educating the public in resource conservation & enhancement, and providing technical expertise.

2. What is the Mobile Water Lab? Free service offered by the Yolo RCD Includes: Irrigation Evaluations  Optional Source Water Quality Testing  Recommendation on Irrigation Management  Water Quality Management Practices

3. Application Efficiency and Distribution Uniformity Deprive portions of the crop of needed water Over-irrigate portions of the field A Non-Uniform Distribution can:

4. Irrigation Evaluations provide: Analysis of the system distribution uniformity (defined as a measure of the uniformity with which irrigation water is distributed to different areas in a field) Determination of application rates Qualitative observations of clogging and emitter wear System map of pressure and flow measurements Suggestions for system improvements and maintenance

5. District Programs multi-benefit/water quality Water Use Efficiency (WUE) – funding for irrigation evaluations (through Mobile Water Lab) – 10 more NRCS – AWEP (Ag Water Enhancement Program), greater water quality emphasis in 2010, many practices: Pipelines, drip, vegetated systems, sediment traps, etc. CARCD – AWEP: many central valley counties Glenn, Colusa, Yolo, Solano, Sutter, San J, Stanislaus, Merced, Fresno, Kings, Tulare, Kern Water Use Efficiency vs benchmark 25.5 A-inches Tomato, tracking/documenting yield & solids

6. District Programs (cont.) multi-benefit/water quality Yolo-Solano Conservation Partnerships on working lands: Ditch vegetation (with/for irrigation districts) Riparian buffers/reveg – filtering irrigation/storm runoff Cache Creek Geomorphic Assessment & Local Youth Stream Monitoring Capay Valley Riparian Vegetation Management Yolo County Weed Management Area (with Yolo Ag Dept) Yolo-Solano Ag Water Quality Support Program Grant closed, some money for practices went unused.
