Summary
Designed by the USDA NRCS and completed in 2006, this earth dam stands at a height of 26 feet and has a storage capacity of 151 acre-feet. With a low hazard potential and a moderate risk assessment rating, this structure plays a vital role in protecting the surrounding area from potential flooding events.
Operated and regulated by the Iowa Department of Natural Resources, East Fork Grand River Watershed Site E-43 is equipped with an uncontrolled spillway and serves as a crucial component of water resource management in the region. The dam's primary purpose is flood risk reduction, reflecting its importance in safeguarding the local community and environment from the impacts of extreme weather events. Despite its condition being rated as "Not Rated" in terms of assessment, the structure continues to fulfill its intended function effectively.
Situated in a picturesque setting with a drainage area of 0.49 square miles, East Fork Grand River Watershed Site E-43 showcases the intersection of infrastructure and natural landscapes. With its strategic location and dedicated purpose, this dam serves as a testament to the ongoing efforts to enhance water resource management and climate resilience in the region.

Dam Data Reference
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.
