Summary
This earth dam, completed in 1966, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a height of 33 feet and a length of 454 feet, the dam has a storage capacity of 129 acre-feet and covers a surface area of 7.2 acres.
Situated on the TR-Walnut Creek, this dam is regulated by the Iowa Department of Natural Resources (DNR) and is inspected, permitted, and enforced by the state. Despite its low hazard potential, the dam has a moderate risk assessment of 3, highlighting the importance of ongoing risk management measures. The Reed Subwatershed Sta 97+82 is a significant component of the local water infrastructure, providing essential services while also contributing to the overall ecological health of the region.
Managed by the USDA NRCS, this dam represents the intersection of water resource management and climate resilience in the region. Its strategic location, purposeful design, and regulatory oversight underscore the importance of sustainable water infrastructure for both human and environmental well-being. As water resource and climate enthusiasts continue to monitor and advocate for responsible water management practices, the Reed Subwatershed Sta 97+82 serves as a valuable case study in the intersection of water resource management, climate adaptation, and community resilience.

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.
