  1. The Role of Water in Salmonid Recovery Do fish really need water, and if so, how much and when???

  2. If fish could weigh in on this…

  3. What water means to fish The medium IS the message… The right flow conditions at the right time of year for each life stage Flows are also important in shaping the stream in which fish live Sediment and LWD transport In-stream complexity

  4. Water needs for Salmonids Water quantity Adequate flows for each life stage throughout the year Water quality Temperature, Sediment, pH, etc Flow properties Range of velocities in winter (flow refuge) Migration flows Turbidity

  5. Stream Habitat by life stage Egg (spawning gravels) Fry (spawning gravels) Juvenile (pools, in-channel, side channel and off-channel) Smolt (lagoons and larger off-channel ponds) Adult Spawner (spawning gravels)

  6. Fish Habitat by Season Wintering Rearing Habitat (high flow refugia, boulder shadows, low velocity eddys, overhangs) Summer Rearing Habitat (temperature refugia, overhangs, riparian cover, sometimes isolated pools)

  7. In-stream Flow in Summer

  8. Alternatives to summer in-stream water withdrawals

  9. Rainwater Harvesting Potential in CA

  10. Salmon Creek Save our Salmon Project

  11. Napa and Suisun Creek Watersheds Napa and Suisun Creek tributaries Agricultural and Rural Residential Uses Solano RCD Napa RCD CA Land Stewardship Institute (FFF) Municipalities

  12. Sonoma Creek Potential Sonoma Creek tributaries Agricultural and Rural Residential Uses Sonoma Ecology Center Southern Sonoma RCD Municipalities

  13. Other Alternatives for water supply Recycled Water Desalinization Other innovations

  14. Key watersheds for Steelhead Recovery in the North Bay Napa River Sonoma Creek Petaluma River
