Summary
Managed by the local government and designed by the USDA NRCS, this Earth dam stands at a height of 34 feet and has a length of 500 feet. Completed in 2010, it serves multiple purposes including fish and wildlife habitat creation, grade stabilization, and recreation in addition to flood risk reduction. With a storage capacity of 128 acre-feet, the dam plays a vital role in managing water resources in the area.
Situated in the tributary to East Fork Grand River, this site covers a drainage area of 0.42 square miles and has a surface area of 5 acres. Despite its low hazard potential, the dam has not been rated for its condition assessment. It is regulated and permitted by the Iowa DNR, ensuring that it meets state inspection and enforcement standards. With a primary focus on flood risk reduction, East Fork Grand River Watershed Site B-62 exemplifies the importance of sustainable water resource management and climate resilience efforts in the region.
The dam's location in the State of MO within Ringgold County, Iowa, underscores its significance in protecting the local community from potential flood events. Supported by federal funding and designed by the Natural Resources Conservation Service, this structure represents a collaborative effort to enhance water resource infrastructure and promote environmental conservation. As climate change continues to impact water systems, East Fork Grand River Watershed Site B-62 serves as a valuable asset in safeguarding the area's natural and built environment for future generations.

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.
