Sly Creek reservoir
Sly Creek
Sly Creek Reservoir is a man-made lake located in the northern Sierra Nevada mountain range of California. The history of the reservoir began in 1960 when the Feather River Hydroelectric Project was constructed. The reservoir is primarily used to generate hydroelectric power, store water for downstream agricultural and municipal use, and provide recreational opportunities such as fishing, boating, and camping. The Sly Creek watershed, which feeds the reservoir, is predominantly forested and consists of granite outcrops and meadows. The watershed is also home to several important plant and animal species, including the Pacific fisher and northern goshawk. The reservoir’s primary source of water is from snowpack, which typically begins to melt in April and peaks in May or June. The reservoir is a vital component of California’s water supply system and plays an important role in meeting the state’s water demands.

About Sly Creek
Where does the data for Sly Creek 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.
