Summary
This earth dam, standing at a height of 30 feet and a length of 478 feet, serves multiple purposes including fire protection, stock watering, small fish pond, and flood risk reduction. Situated on the TR-Chariton River, this dam has a drainage area of 0.33 square miles and a storage capacity of 111 acre-feet. Despite being classified as low hazard potential with a moderate risk assessment, the dam has not been rated for its condition assessment.
The Moulton Watershed Site A-3 is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement processes. The dam has a spillway type of uncontrolled and a surface area of 8 acres. The primary purpose of this dam is to provide essential water resources for fire protection and livestock, while also contributing to flood risk reduction efforts in the area. With David Loebsack representing the area in Congress, this dam plays a crucial role in managing water resources and protecting the local community from potential hazards.

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.
