About this reservoir

Prosser C Res Nr Truckee Ca

Prosser Creek Reservoir is located in Truckee, California, and is a popular recreational area for fishing, boating, and camping. The reservoir was built in 1962 as part of the Truckee River Storage Project, which aimed to provide water for irrigation, power generation, and municipal use. The reservoir is fed by Prosser Creek, which is a tributary of the Truckee River, and its hydrology is heavily influenced by the area's snowpack providers. The reservoir is managed by the Truckee Donner Public Utility District, which also operates a hydroelectric power plant on the dam. In addition to its recreational uses, the reservoir is also used to provide water for nearby agricultural and municipal needs.

FAQ

About Prosser C Res Nr Truckee Ca

Where does the data for Prosser C Res Nr Truckee Ca 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.
