Shadow Mountain Reservoir reservoir
Shadow Mountain Reservoir
Shadow Mountain Reservoir is located in Grand County, Colorado and is a man-made lake created in the early 1940s. The reservoir serves as a storage site for water that is used for agricultural and recreational purposes. The reservoir is fed by the Colorado River and its tributaries, as well as by snowpack from the surrounding mountains. The water is managed and distributed by the Bureau of Reclamation, and the Northern Colorado Water Conservancy District. Shadow Mountain Reservoir is popular for boating, fishing, and camping, and is surrounded by mountains that provide opportunities for hiking and skiing. The reservoir is also a vital source of water for the surrounding agricultural community, providing irrigation water to farmers throughout the region.

About Shadow Mountain Reservoir
Where does the data for Shadow Mountain 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.
