There is no real time gauge currently available, however, a real time gauge will be provided as part of the new settlement with SMUD.
Historical daily average flows are available from the USGS #11441500 gauge page (SF Silver Creek Near Ice House). SMUD generally keeps total control of flows in this reach. On very rare occasions high flows of over 1,000 cfs have occurred. See this Table of Flows in 1996-97. The spills of '96 & '97 were brought back to minimum releases within a few days. Minimum instream releases appear to range from about 3.3 cfs, up to about 10 cfs. Other than the minimum release, SMUD diverts the entire flow of the SF Silver Creek to the Jones Fork Powerhouse and then into Union Valley Reservoir on the main fork Silver Creek. Jones Fork Powerhouse appears to have a maximum capacity of around 260 cfs.
Boatable releases of up to 500 cfs have happened in October of some years. AW volunteers will announce releases here and on various forums when they find out about them.
Reports give the public a chance to report on river conditions throughout the country as well as log the history of a river.
