Horsetooth Reservoir reservoir
Horsetooth Reservoir
Horsetooth Reservoir is a popular recreational area in Colorado, located west of Fort Collins. The reservoir was constructed in 1949 by the Bureau of Reclamation for irrigation purposes, and it has since become a significant source of water for the region. Horsetooth Reservoir is fed by several streams, including Spring Creek and the Cache la Poudre River, which provide the majority of the surface flow. Additionally, snowpack from the surrounding mountains contributes to the reservoir's water levels. The reservoir is used for various recreational activities, such as camping, boating, fishing, and hiking. The water is also used to irrigate agricultural land in the area, supporting the local farming industry.

About Horsetooth Reservoir
Where does the data for Horsetooth 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.
