Little Grass Valley reservoir
Little Grass Valley
Little Grass Valley Reservoir is a lake located in Plumas County, California, USA. The reservoir was created by the construction of Little Grass Valley Dam, which was completed in 1961 by Pacific Gas and Electric Company. The dam is 105 feet high and 1,610 feet long. The reservoir has a capacity of 105,000 acre-feet and is part of the North Fork Feather River watershed. It is fed by the Little Grass Valley Creek and other small creeks, and provides water for irrigation, domestic, and industrial use. The reservoir is also used for recreational activities like fishing, boating, and swimming. The surrounding area has many campgrounds and hiking trails. Little Grass Valley is an important source of water for the region and is managed by the Plumas County Water Agency.

About Little Grass Valley
Where does the data for Little Grass Valley 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.
