Summary

1 Dam, located in Jefferson, Ohio, is a privately owned structure designed in consultation with the USDA and SCS engineer, Bill Spencer. Completed in 1966, this earth dam serves primarily for recreational purposes and boasts a height of 39.1 feet, a length of 465 feet, and a storage capacity of 356 acre-feet. The dam is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections to ensure its safety and functionality.

With a low hazard potential and a satisfactory condition assessment, Jefferson Sportsman's Lake No. 1 Dam provides a tranquil setting for outdoor enthusiasts and climate aficionados alike. The dam's maximum discharge capacity of 1085 cubic feet per second, coupled with a surface area of 25.6 acres and a drainage area of 1.17 square miles, contributes to the ecological health of the region. Its location near a tributary to McIntyre Creek offers a scenic backdrop for recreational activities while serving as a vital water resource for the surrounding community.

As a key component of the local water infrastructure, Jefferson Sportsman's Lake No. 1 Dam plays a crucial role in water management and conservation efforts in the area. Its regular inspections, satisfactory condition, and low hazard potential underscore its importance in ensuring the safety and sustainability of the region's water resources. Enthusiasts of water resources and climate will find this dam a captivating example of how human-made structures can harmoniously coexist with the natural environment to benefit both wildlife and 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
