Summary

The dam stands at a height of 28 feet and has a length of 356 feet, providing a storage capacity of 46 acre-feet for purposes such as fire protection and maintaining a small fish pond. The dam is classified as an earth dam with a soil foundation and is regulated by the Iowa Department of Natural Resources.

The dam's hazard potential is rated as low, with a moderate risk assessment score of 3. Although the dam has not been recently inspected and its condition is not rated, it meets state regulatory requirements for permitting, inspection, and enforcement. The spillway type is uncontrolled, and the dam has a surface area of 3.3 acres, serving a drainage area of 0.21 square miles. Despite the lack of specific data on the dam's risk management measures and emergency action plan, its overall risk level is considered moderate.

Kent Dam's location within the Kansas City District and its association with the USDA NRCS as the designer reflect a commitment to water resource management and conservation. With its primary purpose being fire protection and stock maintenance, the dam plays a crucial role in supporting local water supply and ecosystem health. As climate change impacts water resources, understanding and maintaining infrastructure like Kent Dam is essential for ensuring sustainable water management practices in the region.

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.
