Williams Fork Reservoir
Williams Fork Reservoir is a man-made lake located in Grand County, Colorado. It was created in 1959 by the construction of the Williams Fork Dam, which was built to provide hydroelectric power and irrigation water to the surrounding areas. The reservoir has a capacity of 97,000 acre-feet and is fed by the Williams Fork River and several small tributaries. The river's flow is highly variable, and the reservoir serves as a buffer against droughts and floods. The reservoir's water is also used for agriculture, including hay production and grazing. Recreation activities on the reservoir include fishing, boating, camping, and hiking. The area is also popular for snowmobiling and cross-country skiing during the winter months. The reservoir is managed by the Colorado River Water Conservation District.

About Williams Fork Reservoir
What is the water level at Williams Fork Reservoir right now?
As of August 9, 2026, Williams Fork Reservoir is holding 33,967 acre-ft, about 43% of normal for this date. Pool elevation and the year-over-year trend are shown above.
Is Williams Fork Reservoir high or low right now?
Compare the percent-of-normal figure on this page: above 100% means storage is higher than the historical average for the date (a wet year), below 100% means lower (a dry year or drought). The daily-levels chart shows the current trend.
Where does the data for Williams Fork 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.
