Stony Gorge Reservoir reservoir
Stony Gorge Reservoir
Stony Gorge Reservoir is a man-made lake located in the Sacramento Valley in California. The reservoir was created in 1962 by the Stony Gorge Dam, which is used for irrigation and flood control. The reservoir has a storage capacity of 93,000 acre-feet and covers an area of 7.5 square miles.
The hydrology of Stony Gorge Reservoir is primarily fed by the East Branch of the Stony Creek, which is a major tributary of the Sacramento River. The reservoir also receives water from the snowpack in the nearby mountains.
The reservoir serves as a surface water source for agricultural uses in the surrounding region. In addition, the reservoir is a popular destination for recreational activities such as boating, fishing, and camping. The reservoir is managed by the United States Bureau of Reclamation.

About Stony Gorge Reservoir
Where does the data for Stony Gorge Reservoir 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.
