About this reservoir

Camanche Reservoir

Camanche Reservoir in California is a man-made lake located in the foothills of the Sierra Nevada Mountains. It was created in 1963 when the Camanche Dam was built across the Mokelumne River. The reservoir is used for hydroelectric power generation, irrigation, and recreation. Its hydrology is primarily dependent on snowmelt from the surrounding mountains and surface flow from the Mokelumne River. The river is also a significant source of water for agricultural purposes in the region. Recreational activities such as boating, fishing, and camping are popular at the reservoir, which has several marinas and campgrounds. The lake is stocked with a variety of fish, including bass, trout, and catfish. The Camanche Reservoir is an important source of water and recreation for the local community.

Detailed forecast

Plan around the weather

Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

FAQ

About Camanche Reservoir

Where does the data for Camanche Reservoir come from?

Daily storage, pool elevation, and release rates are sourced from USGS, USBR, and USACE monitoring stations. Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

Storage observations are updated daily by the operating agency. The 15-day weather forecast refreshes throughout the day. Snoflo caches and renders the most recent observation -- check the "as of" timestamp on the storage card.

What does the Hazard hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this reservoir, set a threshold, and you'll get a push the moment conditions cross.
