Mount Gilead Lower Lake Dam dam
Mount Gilead Lower Lake Dam
Mount Gilead Lower Lake Dam, located in Morrow, Ohio, is a state-regulated earth dam completed in 1930 by the Ohio Department of Agriculture. With a height of 20 feet and a length of 525 feet, the dam serves primarily for recreational purposes, offering a surface area of 11.4 acres and a storage capacity of 95 acre-feet. Situated on Sams Creek, the dam is designed to withstand a maximum discharge of 2600 cubic feet per second.
Despite being classified as having a high hazard potential, the dam was assessed as satisfactory during its last inspection in 2012. The Department of Natural Resources in Ohio oversees the regulatory aspects of the dam, including permitting, inspection, and enforcement. With a history of regular inspections every 5 years and an emergency action plan in place, Mount Gilead Lower Lake Dam remains a vital water resource in the region, providing both recreational opportunities and essential flood control measures for the community.
In the hands of the state government, Mount Gilead Lower Lake Dam continues to be a key feature in the local landscape, managed with diligence and care to ensure its safety and efficacy. As water resource and climate enthusiasts, it is crucial to acknowledge the importance of such infrastructure in sustaining a balanced ecosystem and safeguarding against potential risks associated with dam failures. With ongoing monitoring and maintenance, Mount Gilead Lower Lake Dam stands as a testament to responsible water resource management in Ohio.

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 Mount Gilead Lower Lake Dam
Where does the data for Mount Gilead Lower Lake 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.
