Kerckhoff Reservoir reservoir
Kerckhoff Reservoir
Kerckhoff Reservoir is a man-made lake located in the Sierra Nevada Mountains of California. It was constructed in the early 1900s as part of the San Joaquin River Hydroelectric Project. The reservoir is fed by the San Joaquin River and its tributaries, as well as by snowmelt from the surrounding mountains. This makes it an important source of water for irrigation and hydroelectric power generation in the Central Valley region of California. The reservoir also provides recreational opportunities such as fishing, boating, and camping. The area surrounding the reservoir is used for agricultural purposes, including growing crops such as almonds, grapes, and citrus fruit. The water levels in the reservoir are closely monitored and managed to ensure a reliable water supply for both agricultural and urban users.

About Kerckhoff Reservoir
Where does the data for Kerckhoff 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 below 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.
