Jefferson Sportsman's Lake No. 1 Dam dam
Jefferson Sportsman's Lake No. 1 Dam
Jefferson Sportsman's Lake No. 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.
Dam data reference
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 Jefferson Sportsman's Lake No. 1 Dam
Where does the data for Jefferson Sportsman's Lake No. 1 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 Low 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.
