Summary
It serves as a water resource infrastructure along the TR- Donnelly Creek, providing a storage capacity of 65 acre-feet and a normal storage of 44 acre-feet. The dam is owned and regulated by the local government and falls under the jurisdiction of the Iowa Department of Natural Resources.
The dam has a spillway type of uncontrolled and is classified with a significant hazard potential. While its condition assessment is not rated, the risk assessment is moderate. The dam's purpose is primarily for water resource management, with a focus on other associated purposes. It is designed by Stanley Consultants and is subject to state permitting, inspection, and enforcement by the Iowa DNR. Overall, the Muscatine Power & Water Dam plays a crucial role in water management and environmental protection in the area.
With its strategic location in Muscatine, Iowa, the Muscatine Power & Water Dam contributes to the sustainable utilization of water resources in the region. As a key earth dam structure along the TR- Donnelly Creek, it not only provides essential water storage but also helps mitigate flood risks and ensure water quality. The dam's construction, operation, and maintenance are closely monitored by state regulatory agencies to ensure its integrity and safety for the surrounding communities. Climate enthusiasts and water resource professionals can appreciate the vital role that the Muscatine Power & Water Dam plays in preserving the local ecosystem and supporting sustainable water management practices.

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.
