About this reservoir

Barrett

Barrett is a reservoir located in San Diego County, California. It was constructed in the early 1900s to provide water for the city of San Diego. The reservoir is situated in a watershed that covers approximately 40 square miles and is fed by the Barrett Creek, which originates in the Laguna Mountains. The hydrology of the area is influenced by the Mediterranean climate, with most of the rainfall occurring in the winter months. The reservoir provides water to the city of San Diego, as well as to local farmers for irrigation. Recreational activities such as fishing, boating, and camping are also popular in the area. The snowpack providers in the region include the nearby mountains, which provide snowmelt runoff into the reservoir. The surface flow in the area is primarily provided by the Barrett Creek.

FAQ

About Barrett

Where does the data for Barrett 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.
