Summary
Completed in 2010, this earth dam stands at a height of 23 feet and spans 447 feet in length, providing a storage capacity of 176 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," the dam serves as a vital resource for managing sediment and debris in the tributary to South Turkey Creek.
Maintained by the Iowa Department of Natural Resources, the Meadow Lake Sediment Detention Dam plays a crucial role in protecting the surrounding environment and water resources. With a normal storage capacity of 89 acre-feet and a maximum discharge of 30 cubic feet per second, the dam helps regulate water flow and reduce the risk of flooding downstream. Despite its low hazard potential, the dam's strategic location and design make it a key asset for maintaining water quality and ecosystem health in the region.
As an essential part of Iowa's water infrastructure, the Meadow Lake Sediment Detention Dam underscores the importance of sustainable water resource management. With its effective debris control measures and state-regulated enforcement, the dam exemplifies a proactive approach to mitigating the impacts of sedimentation and ensuring the long-term health of the watershed. Climate and water resource enthusiasts can appreciate the role of this structure in preserving the natural environment and enhancing resilience to climate change.

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.
