About this reservoir

Antelope Lake

Antelope Lake is a reservoir located in Plumas County, California. The lake was created in 1960 by the construction of the Antelope Dam. The hydrology of the lake is largely fed by the Indian Creek and Last Chance Creek watersheds, which provide surface flow and snowpack runoff. The lake serves as a critical water source for agricultural purposes, providing irrigation for the surrounding ranches and farms. Additionally, the lake is a popular recreational destination, offering opportunities for fishing, boating, and camping. The lake has a capacity of 358,650 acre-feet and covers an area of 4,466 acres when full. The lake is managed by the U.S. Forest Service and is part of the Plumas National Forest.

Plan around the weather

Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

FAQ

About Antelope Lake

Where does the data for Antelope Lake 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.
