Summary

Owned by a private entity, the dam is regulated by the Iowa Department of Natural Resources and is inspected, permitted, and enforced by state agencies. The dam, with a height of 32 feet and a length of 400 feet, holds a normal storage capacity of 63 acre-feet and a maximum storage capacity of 98 acre-feet.

Situated on Mud Creek, Moore Dam poses a low hazard potential and has a moderate risk assessment rating. Although the dam is of earth type construction with a soil foundation, it is not currently rated for condition assessment. The dam has an uncontrolled spillway type with no outlet gates and has not been modified since its completion. Despite its relatively small size and storage capacity, Moore Dam plays a crucial role in providing water resources for fire protection and supporting local wildlife in the area.

Water resource and climate enthusiasts will find Moore Dam to be an interesting structure due to its unique purpose and location in Henry County, Iowa. With its moderate risk assessment and low hazard potential, the dam serves as a valuable asset for the community while also highlighting the importance of proper dam management and inspection protocols to ensure public safety and environmental conservation.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
