Summary
This site, managed by the local government, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. Constructed in 1973 by the USDA NRCS, this Earth dam stands at a height of 38 feet and has a storage capacity of 409 acre-feet, with a normal storage of 76 acre-feet and a surface area of 8.6 acres.
The dam, designed for low hazard potential, is regulated by the Iowa DNR and undergoes regular state inspection and enforcement to ensure its safety and functionality. Ledgewood Creek Watershed Site M-5 is a critical infrastructure for water management in the area, with a drainage area of 1.5 square miles and a maximum discharge capacity. The site is located along the TR-Ledgewood Creek and is part of the Omaha District for water resource management.
Overall, Ledgewood Creek Watershed Site M-5 plays a key role in water resource management in the region, providing essential services for fire protection, stock, and flood risk reduction. With a moderate risk assessment rating, the site is closely monitored and maintained to ensure its effectiveness in water storage and management. The collaboration between local government, USDA NRCS, and Iowa DNR highlights the importance of proactive measures in safeguarding water resources and infrastructure for the community.

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.
