Lake Almanor reservoir
Lake Almanor
Lake Almanor is a large reservoir situated in Plumas County, California. The lake was formed as a result of damming of the Feather River in 1914. It has a surface area of 28,000 acres and a maximum depth of 90 feet. The lake is fed by several small creeks and the North Fork Feather River. The snowpack from Mount Lassen National Park provides a significant portion of the lake's water supply. The lake's water is primarily used for irrigation and hydroelectric power generation. The lake is also a popular recreational destination for boating, fishing, and camping. The area surrounding the lake is home to several species of wildlife, including bald eagles, ospreys, and black bears. Overall, Lake Almanor serves as an important source of water and a popular tourist destination in Northern California.

About Lake Almanor
Where does the data for Lake Almanor 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 below 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.
