Summary
This local government-owned earth dam stands at a height of 33 feet and has a structural height of 336 feet, with a storage capacity of 106.5 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition, and inspection frequency is currently listed as zero.
This uncontrolled spillway dam with a spillway width of 40 feet is designed to handle a maximum discharge of 279.4 cubic feet per second. While the dam remains unregulated by the state and does not require permitting or inspections, it is crucial for protecting the surrounding area from potential flooding events. Although the dam's hazard potential is low, its risk assessment is moderate, indicating the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in flood risk reduction.
The East Fork Grand River Dam F-26 serves as a vital infrastructure for flood risk management in the region, with a primary purpose of protecting the local community from potential flooding along Lotts Creek. Its location in a moderate-risk area underscores the importance of regular monitoring and maintenance to ensure its continued functionality and effectiveness in mitigating flood risks. As a pivotal piece of water resource management infrastructure, this dam plays a crucial role in safeguarding the community and environment against the impacts of extreme weather events and climate change.

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.
