Fox Lake dam
Fox Lake
Nestled in the picturesque city of Whiterocks, Utah, Fox Lake stands as a testament to the state's commitment to water resource management. Owned privately, this reservoir is regulated by the Utah Division of Water Rights, ensuring that its irrigation purposes are met with precision. Built in 1927, Fox Lake boasts a significant hazard potential with a structural height of 19 feet and a hydraulic height of 16 feet, providing a maximum storage capacity of 1400 acre-feet.
Situated along Shale Creek, Fox Lake plays a crucial role in the local ecosystem, serving as a vital source of water for agricultural activities in Duchesne County. With a drainage area of 3 square miles, this earth dam stretches over 1083 feet and holds a normal storage capacity of 1126.15 acre-feet. Despite its age, Fox Lake has not been rated for its condition, underscoring the need for regular inspection and maintenance to ensure its long-term sustainability.
While Fox Lake lacks certain detailed information such as the spillway type and width, its historical significance and strategic location make it a key player in Utah's water infrastructure. With the potential to impact downstream communities in case of emergencies, efforts to assess and manage risks associated with the reservoir are crucial for safeguarding its integrity and functionality for future generations of water resource and climate enthusiasts.

About Fox Lake
Where does the data for Fox Lake come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant 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 dam, set a threshold, and you'll get a push the moment conditions cross.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.
