About this reservoir

Vallecito Reservoir

Vallecito Reservoir is a popular recreational destination located in southwestern Colorado. The reservoir was formed in 1941 after the construction of the Vallecito Dam on the Pine River. The reservoir has a capacity of 125,000 acre-feet and is used for irrigation, municipal water supply, and recreation. Surface flow from the Pine River and nearby creeks provide water to the reservoir, while snowpack from the surrounding San Juan Mountains also contributes to the water supply. The reservoir is a popular destination for fishing, boating, camping, and hiking, and is surrounded by the San Juan National Forest. The reservoir also supports local agriculture, primarily in the form of hay farming. Despite being impacted by drought in recent years, Vallecito Reservoir remains an important source of water and recreation for the surrounding community.

FAQ

About Vallecito Reservoir

Where does the data for Vallecito 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.
