Big Sandy Reservoir reservoir
Big Sandy Reservoir
Big Sandy Reservoir is a man-made reservoir located in Sweetwater County, Wyoming. The reservoir was built in 1963 as part of the Seedskadee Project, which was a joint effort by the Bureau of Reclamation and the state of Wyoming to provide irrigation water to the Green River Valley. The reservoir covers an area of 2,500 acres and has a storage capacity of 40,000 acre-feet. The hydrology of the reservoir is primarily dependent on snowmelt and surface water from the Big Sandy River and Bull Lake Creek. The reservoir is used for agricultural irrigation, recreation, and wildlife habitat. It is a popular destination for camping, fishing, and boating, and is home to a variety of fish species including rainbow trout, brown trout, and kokanee salmon.

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.

About Big Sandy Reservoir
Where does the data for Big Sandy 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.
