About this reservoir

Stateline Reservoir

Stateline Reservoir is a man-made reservoir located in Utah that was created in the 1950s to store water from the Bear River for irrigation purposes. The reservoir has a capacity of 42,300 acre-feet and is managed by the State of Utah's Division of Water Resources. The reservoir is fed by several surface flows, including the Bear River and the Little Bear River, as well as by snowpack meltwater. The water from the reservoir is primarily used for agricultural irrigation, with some water also being used for recreational activities such as fishing and boating. Despite its importance for agriculture in the area, the reservoir has faced challenges in recent years due to drought and the over-allocation of water rights.

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 Stateline Reservoir

Where does the data for Stateline Reservoir 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.
