San Vicente reservoir
San Vicente
San Vicente is a reservoir located in San Diego County, California, USA. The dam was constructed in 1943, and it is the largest in the county, standing at 220 feet tall and 1.5 miles long. The reservoir has a capacity of over 90,000 acre-feet of water, which is primarily used to supply drinking water to the San Diego region. The hydrology of San Vicente is complex, with a combination of surface flow from nearby mountain streams and snowpack melt providing the water source. The San Diego County Water Authority manages the reservoir, while the San Diego County Water District operates the hydroelectric power plant located at the dam. The area surrounding San Vicente is mainly agricultural, with citrus and avocado crops dominating the landscape. Recreational activities such as fishing, boating, and hiking are also popular in the area.

About San Vicente
Where does the data for San Vicente 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.
