Shasta Dam (Usbr) reservoir
Shasta Dam (Usbr)
Shasta Dam, located on the Sacramento River in northern California, was built by the United States Bureau of Reclamation (USBR) in the 1940s. The dam was constructed primarily for flood control, irrigation, and hydroelectric power generation. It is the seventh-largest dam in the United States and the second-largest in California. The reservoir created by the dam, Shasta Lake, has a capacity of 4.5 million acre-feet of water and is a major source of water for central and southern California. The hydrology of the area is heavily influenced by snowpack in the surrounding mountains, which provides much of the water that fills the reservoir. The dam and reservoir also support recreational activities such as boating and fishing, and provide water to support agricultural production in the region.

About Shasta Dam (Usbr)
Where does the data for Shasta 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.
