Leesville Dam dam
Leesville Dam
Leesville Dam, also known as Leesville Lake, is a federal-owned structure located in Sherrodville, Ohio. Built in 1937 by the US Army Corps of Engineers, this earth dam stands at a structural height of 74 feet and has a hydraulic height of 63 feet. With a primary purpose of flood risk reduction, Leesville Dam also serves recreational and fish and wildlife pond purposes, storing a normal capacity of 19,500 acre-feet of water in its 1,000-acre surface area.
The dam, located on McGuire Creek, has an uncontrolled spillway with a width of 150 feet and is equipped with three slide (sluice gate) outlet gates. It poses a high hazard potential and undergoes inspections every five years to ensure its safety and functionality. The US Army Corps of Engineers actively manages the dam-related flood risks by monitoring its condition, prioritizing risk-mitigating activities, and engaging with emergency managers and the public to raise awareness and preparedness for potential emergencies.
In the face of severe weather events and inconsistent water inflows, Leesville Dam plays a crucial role in managing water levels and maintaining structural integrity. As part of its risk management measures, the US Army Corps of Engineers continually updates the emergency action plan, conducts regular maintenance and repairs, and collaborates with local emergency managers to ensure the safety and resilience of the dam and surrounding communities.

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 Leesville Dam
Where does the data for Leesville 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.
