About this reservoir

Lake Ellsworth Near Elgin

Lake Ellsworth is a man-made reservoir located near Elgin, Oklahoma. It was constructed in 1962 by the U.S. Army Corps of Engineers as part of the Cache Creek Flood Control Project. The lake provides flood control, irrigation, and recreational opportunities for the area. It has a surface area of 5,200 acres and a maximum depth of 87 feet. The main source of water for the lake is Cache Creek, which flows into the lake from the north. Snowmelt and rainfall also contribute to the lake's water supply. The lake is used for fishing, boating, and swimming, and there are several campgrounds and picnic areas located along its shores. Agriculture is an important industry in the area, and the lake is used for irrigation purposes.

FAQ

About Lake Ellsworth Near Elgin

Where does the data for Lake Ellsworth Near Elgin 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.
