About this reservoir

Eden Reservoir

Eden Reservoir is located in southwestern Wyoming and was constructed in 1907 to provide water for irrigation and mining. The reservoir has a capacity of 7,170 acre-feet and is fed by both surface flow and snowpack. The primary surface flow provider is the Hams Fork River, while the snowpack is provided by the surrounding mountains. The reservoir supports agricultural activities in the surrounding area, including crops like alfalfa and sugar beets. Additionally, the reservoir also provides recreational opportunities such as fishing, boating, and camping. The reservoir is managed by the Eden Irrigation District and is crucial to the local economy and ecosystem.

Detailed forecast

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 Eden Reservoir

Where does the data for Eden 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 below 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.
