About this reservoir

Buck Island Lake

Buck Island Lake is a man-made reservoir located in the northern Sierra Nevada mountains in California, USA. It was created in the 1960s as part of the Buckhorn Hydroelectric Project, which was designed to generate electricity for Pacific Gas and Electric (PG&E). The lake is fed by several creeks, including Buckhorn Creek and a diversion from the Middle Yuba River, and its water is used to generate hydroelectric power. The reservoir is also used for recreational activities such as hiking, fishing, and camping. The surrounding area is primarily forested and there are no agricultural uses for the lake. Snowpack provides water for the lake during the winter months, and the lake serves as a source of water for downstream communities during the dry season. Buck Island Lake is an important source of hydroelectric power and a popular destination for outdoor enthusiasts.

FAQ

About Buck Island Lake

Where does the data for Buck Island Lake 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.
