Summary
This site serves multiple purposes, including fire protection, stock maintenance, and small fish pond support, as well as flood risk reduction. The dam, completed in 1973, stands at a height of 27 feet and has a storage capacity of 228 acre-feet, with a normal storage level of 61 acre-feet over a surface area of 9.7 acres.
Managed by the Iowa DNR, this earth dam plays a significant role in the Fremont County water management system, regulating the flow of Ledgewood Creek. With a low hazard potential and a moderate risk assessment rating, the dam is not currently rated for its condition. However, it is subject to state regulation, permitting, inspection, and enforcement to ensure its continued safety and effectiveness in managing water resources in the area. Ledgewood Creek Watershed Site 2-4 is a valuable asset for both environmental conservation and community protection, contributing to the overall resilience of the region's water infrastructure.
Overall, Ledgewood Creek Watershed Site 2-4 stands as a testament to the collaborative efforts between local government agencies, such as the Iowa DNR and USDA NRCS, in ensuring the sustainable management of water resources in the region. With its strategic location and purposeful design, this site not only supports various ecosystem functions but also provides essential services for fire protection, agriculture, and flood risk reduction. As climate change continues to impact water systems, the effective regulation and maintenance of sites like this will be crucial in safeguarding both the environment and local communities against the challenges posed by a changing climate.

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.
