Dewey Dam dam
Dewey Dam
Dewey Dam, also known as Dewey Lake, is a federal-owned structure located in Floyd County, Kentucky. Completed in 1949 by the US Army Corps of Engineers, this Earth-type dam serves multiple purposes including flood risk reduction, fish and wildlife habitat, and recreation. With a structural height of 118 feet and a hydraulic height of 86 feet, Dewey Dam helps to manage water levels on Johns Creek of Levisa Fork.
The dam has a storage capacity of 93,300 acre-feet and covers a surface area of 1,100 acres. Despite its high hazard potential, the USACE implements risk management measures, such as regular inspections, emergency action plans, and maintenance activities, to mitigate potential flood risks associated with the dam. By collaborating with local emergency managers and the public, the USACE ensures the safety and integrity of Dewey Dam for the surrounding community.
As a vital infrastructure for flood control and ecosystem preservation, Dewey Dam stands as a testament to the USACE's commitment to managing water resources effectively and safeguarding communities from potential risks. With ongoing monitoring and maintenance efforts, Dewey Dam continues to play a crucial role in water resource management in the region, demonstrating the importance of sustainable infrastructure development in the face of changing climate conditions.

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 Dewey Dam
Where does the data for Dewey Dam 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.
