Summary
Completed in 2003, this earth dam stands at a height of 27 feet and has a length of 516 feet, providing a maximum storage capacity of 95 acre-feet. Despite its low hazard potential, the dam serves as a crucial barrier for protecting the surrounding area from potential flooding events.
Managed by the local government, East Fork Grand River Dam H-38 operates with uncontrolled spillways and outlet gates, ensuring efficient water flow and discharge during peak periods. The dam's moderate risk assessment highlights the importance of ongoing monitoring and maintenance to ensure its structural integrity and functionality. While not regulated by the state, this dam plays a significant role in safeguarding the Worth County community and supporting water resource management efforts in the region.
With its strategic location and purposeful design, East Fork Grand River Dam H-38 exemplifies the collaboration between federal and local agencies in addressing flood risks and protecting communities from water-related hazards. As a key component of the flood risk reduction system, this earth dam stands as a testament to the importance of sustainable water resource management and climate resilience in safeguarding our natural environment and 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.
