About this reservoir

Whiskeytown Dam (Usbr)

Whiskeytown Dam is a concrete arch dam located in Shasta County, California. It was constructed by the United States Bureau of Reclamation in 1963 for flood control and hydroelectric power generation. The dam impounds the Sacramento River, creating Whiskeytown Lake, which is a popular recreational area for fishing, boating, and swimming. The lake also serves as a source of irrigation for agricultural purposes. The hydrology of the Whiskeytown Dam is dependent on snowpack from the surrounding mountains, which provides a significant portion of the water supply during the dry season. The dam is managed by the Bureau of Reclamation and plays a critical role in the water supply for the surrounding communities.

FAQ

About Whiskeytown Dam (Usbr)

Where does the data for Whiskeytown Dam (Usbr) 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.
