Summary
This earth dam, completed in 1972 by the USDA NRCS, stands at a height of 46 feet and spans 628 feet in length, with a storage capacity of 212 acre-feet. The dam serves to mitigate flood risks in the area, with a drainage area of 0.64 square miles and a surface area of 5 acres.
Maintained by the Iowa Department of Natural Resources, this watershed site is regulated, permitted, inspected, and enforced to ensure its structural integrity and functionality. Despite its low hazard potential, the dam's risk assessment is rated as moderate, indicating a need for ongoing risk management measures. With a controlled spillway and no outlet gates, the dam poses minimal risk to downstream communities, but its condition remains unrated, emphasizing the importance of regular inspections and maintenance to uphold its safety and efficacy.
As a significant water resource in the East Nodaway River area, the Walters Creek Watershed Site 18-2 plays a vital role in water management and conservation efforts. With its strategic location and purposeful design, this earth dam stands as a testament to effective watershed management practices and serves as a valuable asset in maintaining water quality and mitigating flood risks in the region.

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.
