Stevens Creek Reservoir reservoir
Stevens Creek Reservoir
Stevens Creek Reservoir is a man-made reservoir located in the Santa Cruz Mountains of California. The reservoir was created in 1935 by the construction of a dam on Stevens Creek, which is a tributary of the San Francisco Bay. The reservoir is managed by the Santa Clara Valley Water District and serves as a primary drinking water source for the cities of Cupertino, Mountain View, and Sunnyvale. The hydrology of the reservoir is influenced by the surrounding watershed, which includes both surface flow and snowpack from the nearby mountains. The reservoir is also used for recreation, including fishing, boating, and hiking, and there are several agricultural areas surrounding the reservoir. In recent years, the reservoir has experienced lower water levels due to drought conditions and increased water usage.

About Stevens Creek Reservoir
Where does the data for Stevens Creek 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.
