Blue Mesa Reservoir reservoir
Blue Mesa Reservoir
Blue Mesa Reservoir is located in Colorado and was created by the construction of the Blue Mesa Dam in the 1960s. It is the largest body of water in Colorado, with a capacity of 940,000 acre-feet. The reservoir is fed by two primary flow sources, the Gunnison River and the Cimarron River, which provide surface flow into the reservoir. Snowmelt from the surrounding mountains also contributes to the reservoir's water supply. The water from the reservoir is primarily used for agricultural and recreational purposes, including irrigation and fishing. The reservoir is home to a variety of fish species, including kokanee salmon, rainbow trout, and brown trout, making it a popular destination for fishing enthusiasts. Additionally, the reservoir's surrounding area offers opportunities for camping, hiking, and water sports.

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 Blue Mesa Reservoir
Where does the data for Blue Mesa 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.
