Summary
This private-owned earth dam stands at a height of 31.7 feet and has a storage capacity of 126.9 acre-feet, with a normal storage level of 43.8 acre-feet across its 430-foot length. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition and lacks an emergency action plan.
With a spillway width of 40 feet and a maximum discharge capacity of 298 cubic feet per second, East Fork Grand River Dam C-34 ensures the effective management of water flow during periods of high precipitation. The dam's stone core and soil foundation contribute to its structural integrity, making it a reliable asset for flood control efforts in the region. Despite being privately owned, the dam operates without state regulation, inspection, or enforcement, highlighting the need for ongoing monitoring and maintenance to ensure its continued effectiveness in mitigating flood risks.
As an essential component of flood risk reduction infrastructure in the area, East Fork Grand River Dam C-34 plays a crucial role in safeguarding communities along the EF Grand River from potential water-related disasters. Its strategic location, design, and operational features make it a valuable resource for water resource and climate enthusiasts seeking to understand the intersection of infrastructure development and environmental protection in the context of natural hazard management.

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.
