Summary
Built in 1900, this private earth dam primarily serves the purposes of fire protection, stock, and small fish pond management. With a height of 19 feet and a length of 460 feet, the dam holds a maximum storage capacity of 97 acre-feet, providing a surface area of 11 acres for recreational use.
Managed by the Natural Resources Conservation Service, the Coleman Lake Dam boasts a low hazard potential, making it a safe and reliable water resource for the community. Despite not being state regulated, the dam's moderate risk assessment indicates a need for ongoing monitoring and maintenance. With its uncontrolled spillway and outlet gates, the dam presents an ideal setting for water and climate enthusiasts to observe the harmonious coexistence of human-made structures with natural ecosystems.
As a focal point for fire protection and wildlife conservation, the Coleman Lake Dam symbolizes the intersection of human ingenuity and environmental stewardship. Its historical significance, coupled with its modern-day relevance in water management, makes it a compelling site for those interested in exploring the dynamic relationship between water resources and climate adaptation. Visit Coleman Lake Dam to witness firsthand the intersection of past, present, and future in the realm of sustainable water infrastructure.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
