Summary
The dam, designed by the Natural Resources Conservation Service, serves multiple purposes including fire protection and providing a water source for stock or small fish ponds. This Earth-type dam stands at a height of 18.2 feet and has a length of 435 feet, with a storage capacity of 70 acre-feet and a surface area of 7.5 acres.
Although the dam has a low hazard potential, it is currently not rated for its condition assessment. The spillway type is uncontrolled, and the outlet gates are also uncontrolled. The risk assessment for the dam is moderate, with a DSAC assigned date yet to be determined. Despite not being state-regulated or inspected, the dam remains a crucial resource for its primary purposes and continues to support the local ecosystem and water supply in the area.
Overall, Ervin Lake Dam stands as a testament to the importance of private ownership in maintaining water resources and supporting various environmental functions. With its modest size and capacity, the dam plays a vital role in providing water for fire protection and sustaining local wildlife. As climate and water resource enthusiasts, it is essential to recognize the significance of such structures in ensuring water availability and ecosystem health in our communities.

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.
