Summary
This earth dam, completed in 1962 by the USDA NRCS, stands at a height of 30 feet and spans a length of 400 feet, with a storage capacity of 153 acre-feet. The dam is regulated by the Iowa Department of Natural Resources and is designed to reduce flood risks in the area while also serving as a source of water for various agricultural activities.
With a low hazard potential and a moderate risk assessment rating, Moulton Watershed Site B-8 plays a key role in managing water resources in the region. The dam has not been rated for its condition, but it undergoes regular inspections, permitting, and enforcement measures by state agencies to ensure its safety and functionality. The site is situated along the TR-Chariton River and covers a drainage area of 0.7 square miles, making it an essential component of the local water infrastructure.
Despite not having an emergency action plan in place, Moulton Watershed Site B-8 remains a critical feature in the landscape, contributing to water conservation efforts and enhancing the overall resilience of the community to climate-related challenges. As climate enthusiasts and water resource experts continue to monitor and assess the site, its role in mitigating flood risks and supporting various agricultural activities will be of increasing importance in the face of changing environmental conditions.

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.
