About this reservoir

Stewart Lake Outflow Near Jensen

Stewart Lake Outflow is a body of water located near Jensen, Utah. The reservoir has a storage capacity of 10,000 acre-feet of water and was built in 1944. The hydrology of the area is primarily influenced by the Green River and the Uinta Mountains. The outflow from Stewart Lake is an important source of water for agricultural use in the area, particularly for irrigating crops in the nearby towns of Vernal and Jensen. The surface flow into the reservoir is primarily from the Green River, while snowpack melt in the Uinta Mountains also contributes to water levels. The Stewart Lake Outflow is also popular for recreational uses such as fishing and boating.

FAQ

About Stewart Lake Outflow Near Jensen

Where does the data for Stewart Lake Outflow Near Jensen 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.
