Jackson Gulch Reservoir reservoir
Jackson Gulch Reservoir
Jackson Gulch Reservoir is a man-made lake located in the San Juan National Forest of southwestern Colorado. The reservoir was built in 1960 by the U.S. Bureau of Reclamation for the purpose of storing water for irrigation, municipal, and industrial use. The reservoir is fed by snowmelt and surface water runoff from the surrounding mountains, and is also supplemented by the nearby San Juan River. The watershed of the reservoir is approximately 16 square miles, with most of the water coming from the Dolores River. The reservoir is also used for recreational purposes, including fishing, boating, and camping. The area is also known for its winter sports, with nearby ski resorts providing ample snowpack for skiing and snowboarding. The reservoir is an important water source for the surrounding agricultural communities, and supports a variety of crops including hay, alfalfa, and corn.

About Jackson Gulch Reservoir
Where does the data for Jackson Gulch 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.
