Willow Creek Reservoir reservoir
Willow Creek Reservoir
Willow Creek Reservoir is a man-made body of water located in Grand County, Colorado. The reservoir was constructed in 1948 by the Colorado River Water Conservation District for agricultural and municipal purposes. The reservoir has a capacity of 1,100 acre-feet and is fed by Willow Creek, which is a tributary of the Colorado River. The primary purpose of the reservoir is to provide water for irrigation and municipal purposes in the surrounding area. Surface flows into the reservoir come primarily from Willow Creek and snowmelt from the surrounding mountains. The reservoir also provides recreational opportunities such as fishing and boating. It is known for its trout fishing and scenic views of the surrounding mountains. The reservoir is a popular destination for anglers and outdoor enthusiasts in the summer months.

About Willow Creek Reservoir
Where does the data for Willow Creek 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.
