About this reservoir

Foss Reservoir Near Foss

Foss Reservoir is located near Foss, Oklahoma, and was constructed in the 1950s by the U.S. Bureau of Reclamation for flood control and irrigation purposes. The reservoir has a storage capacity of 254,800 acre-feet of water and is fed by the Washita River. The hydrology of the reservoir is influenced by specific surface flows from the Washita River and snowpack providers during the winter months. The reservoir provides irrigation water for agriculture in the surrounding area and also offers recreational activities such as fishing, boating, and camping. The Foss Reservoir Dam, which is approximately 3,500 feet long and 117 feet high, was rehabilitated in the 1990s to ensure its safety and continued use.

FAQ

About Foss Reservoir Near Foss

Where does the data for Foss Reservoir Near Foss 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.
