About this reservoir

San Vicente Res Nr Lakeside Ca

San Vicente Reservoir is located in Lakeside, California, and was constructed in 1943 to provide drinking water for the city of San Diego. It has a capacity of 242,000 acre-feet and is a key component of the region's water supply system. The reservoir is fed by the San Vicente Creek and the Santa Maria River, with surface water primarily provided by the Colorado River via the Colorado River Aqueduct. It also receives snowpack runoff from the Cuyamaca Mountains. The reservoir is used for water supply, hydroelectric power generation, and recreational activities such as boating and fishing. It also supports agricultural uses in the surrounding areas through irrigation. In recent years, the reservoir has been expanded and modernized to improve its water storage capabilities and earthquake resistance.

FAQ

About San Vicente Res Nr Lakeside Ca

Where does the data for San Vicente Res Nr Lakeside Ca 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 above 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.
