Summary
Completed in 2004, this Earth-type dam stands at a height of 12 feet and spans a length of 1070 feet, with a storage capacity of 587 acre-feet. The primary purpose of this dam is to create a Fish and Wildlife Pond, providing habitat for various aquatic species and enhancing the natural environment.
Managed by the Iowa Department of Natural Resources, the Lake Icaria Sediment Detention Dam is designed to regulate water flow from Kemp Creek and prevent sediment buildup, ensuring the health and sustainability of the surrounding ecosystem. With a low hazard potential and a current condition assessment of "Not Rated," this structure plays a crucial role in flood control and water quality management within the region. The dam's spillway width of 265 feet can accommodate a maximum discharge of 9000 cubic feet per second, further demonstrating its capacity for effective water management.
As a state-regulated and inspected structure, the Lake Icaria Sediment Detention Dam exemplifies the collaborative efforts between government agencies and local communities to safeguard water resources and mitigate environmental risks. With its strategic location and design, this dam represents a proactive approach to sustainable water resource management, benefiting both wildlife and residents in the Lake Icaria area.

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.
