East Park Reservoir reservoir
East Park Reservoir
East Park Reservoir is a man-made body of water situated in the foothills of the Northern California Coast Range. It was built by the Bureau of Reclamation in 1967 to store water from Stony Creek, a tributary of the Sacramento River, for agricultural purposes. The reservoir has a capacity of 150,000 acre-feet and covers an area of 11,500 acres. It provides irrigation water to over 36,000 acres of farmland in Colusa and Glenn Counties. The reservoir is also a popular recreational area, attracting campers, anglers, and boaters. The hydrology of the reservoir is primarily dependent on the snowpack in the mountains to the west and the surface flow of Stony Creek. The reservoir is managed by the Bureau of Reclamation, who oversee the water supply and recreation activities.

About East Park Reservoir
Where does the data for East Park 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.
