About this reservoir

Boca Res Nr Truckee Ca

Boca Reservoir is a man-made lake in Truckee, California. It was created in 1939 by the construction of the Boca Dam on the Little Truckee River. The lake has a surface area of 980 acres and can hold up to 40,000 acre-feet of water. It serves as a source of water for the Truckee Meadows Water Authority and provides recreation opportunities for the surrounding communities, including fishing, boating, and camping. The hydrology of the reservoir is heavily influenced by the surrounding snowpack, which provides the majority of the water supply. The Little Truckee River is the primary surface flow provider for the reservoir, but several smaller streams also contribute. The surrounding area is used for agriculture, with hay and cattle grazing being common activities. Overall, Boca Reservoir is an important resource for both water supply and recreation in the Truckee area.

FAQ

About Boca Res Nr Truckee Ca

Where does the data for Boca Res Nr Truckee 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.
