About this reservoir

Silver Jack Reservoir

Silver Jack Reservoir is located in the San Juan Mountains of Colorado and was established in 1957. The reservoir is fed by the snowpack from the surrounding mountains and provides water for irrigation, recreation, and domestic use. The hydrology of the reservoir is primarily determined by the drainage basin and precipitation patterns in the area. The surface flow providers include the Cow Creek and Dallas Creek, while the snowpack providers include the San Juan, Sneffels, and Cimarron Mountains. The reservoir is used for fishing, boating, camping, and hiking, making it a popular destination for outdoor enthusiasts. Additionally, it irrigates agricultural lands in the Uncompahgre Valley, supporting the local farming community.

FAQ

About Silver Jack Reservoir

Where does the data for Silver Jack 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.
