Corn Creek dam
Corn Creek
Corn Creek is a privately owned dam located in Kanosh, Utah, built in 1985 for flood risk reduction on the Corn Creek river. With a hydraulic height of 25 feet and a structural height of 45 feet, the dam stands as a vital structure in the region, providing a storage capacity of 468 acre-feet. The dam is regulated by the Utah Division of Water Rights, ensuring proper inspection, enforcement, and permitting processes are followed to maintain its integrity.
Despite being rated as having a high hazard potential, Corn Creek Dam's condition assessment is deemed fair as of the last inspection in August 2019. The dam serves as a critical flood control measure in Millard County, Utah, protecting surrounding areas from potential inundation during periods of heavy rainfall or snowmelt. Its efficient operation and maintenance are essential to ensure the safety and security of the local community and the preservation of water resources in the region.
With its primary purpose being flood risk reduction, Corn Creek Dam plays a crucial role in managing water flow on the Corn Creek river. Its construction and design as an earth dam highlight the engineering efforts put into mitigating flood risks and safeguarding the environment. As climate change continues to impact water resources, the proper management and upkeep of structures like Corn Creek Dam are essential to adapt to changing weather patterns and ensure water security for future generations.

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.

About Corn Creek
Where does the data for Corn Creek 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 High 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 dam, set a threshold, and you'll get a push the moment conditions cross.
