Summary

Standing at a height of 14 feet with a hydraulic height of 13.75 feet, the dam has a storage capacity of 270 acre-feet and a maximum discharge rate of 1650 cubic feet per second. Despite its low hazard potential and satisfactory condition assessment, the dam is under the regulatory oversight of the Michigan Department of Environment, Great Lakes, and Energy (DEGLE), ensuring regular inspections and enforcement of safety measures.

The controlled spillway of the Parshallville Dam, with a width of 36 feet, helps manage water levels and prevent flooding in the area. The dam's risk assessment indicates a very high risk level, reflecting the importance of implementing effective risk management measures to protect the surrounding community. While the dam may not have a significant impact on federal agencies, it plays a crucial role in providing recreational opportunities and maintaining water resources in the region. With its picturesque location and vital function, the Parshallville Dam stands as a significant asset for water resource and climate enthusiasts to explore and appreciate.

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.
