Summary
Constructed in 1972, this earth-type dam on the tributary of the Grand River boasts a height of 19 feet and a length of 340 feet, with a storage capacity of 52 acre-feet. With state regulation and inspection in place, Ervin Wolff is deemed to have low hazard potential and remains in a condition that is currently not rated.
Despite its unassuming hazard potential, Ervin Wolff plays a crucial role in flood control and water storage in the region, with a maximum discharge capacity of 832 cubic feet per second. Over the years, this dam has continued to serve its primary purpose effectively, ensuring water security for local communities while also mitigating potential risks. Its strategic location and design reflect a commitment to environmental stewardship and resilience in the face of changing climatic conditions.
As a water resource and climate enthusiast, the story of Ervin Wolff serves as a reminder of the importance of sustainable infrastructure in safeguarding our natural resources. With state regulation and inspection protocols in place, this privately-owned dam symbolizes the proactive approach needed to address water challenges in the face of a changing climate. By understanding and supporting structures like Ervin Wolff, we can work towards a more resilient and secure water future for generations to come.

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.
