Summary

Owned by the local government, this earth dam stands at a height of 30 feet and boasts a length of 700 feet, providing recreational opportunities for the community while also storing water for various purposes. With a normal storage capacity of 128 acre-feet and a maximum storage of 571 acre-feet, the dam plays a significant role in managing water resources in the area.

Managed by the Iowa Department of Natural Resources, Rodgers Park Lake Dam has been deemed to have a significant hazard potential, although its condition was assessed as satisfactory during the last inspection in July 2019. The dam's spillway, with a width of 8 feet, is uncontrolled, and the structure is designed to handle a moderate risk level. While the dam has not been modified in recent years, regular inspections are conducted every five years to ensure its safety and functionality.

Despite its significant hazard potential, Rodgers Park Lake Dam continues to provide valuable recreational opportunities and water resource management for the community. With its satisfying condition assessment and regular inspections by the Iowa DNR, the dam stands as a crucial infrastructure for both residents and visitors alike, highlighting the importance of proper maintenance and risk management for water resource and climate enthusiasts in the area.

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.
