Summary
Situated on TR-Turkey Creek, this dam stands at 34 feet tall with a length of 650 feet, providing a storage capacity of 188 acre-feet and covering a surface area of 8.2 acres. Despite its low hazard potential and moderate risk assessment, the dam is not currently rated for condition assessment.
Managed by the Iowa DNR, this watershed site plays a crucial role in flood risk reduction and water resource management in the region. With state jurisdiction, permitting, inspection, and enforcement in place, the dam ensures the safety and sustainability of the surrounding area. As part of the Omaha District, the site is actively regulated and monitored to meet state requirements and guidelines.
For water resource and climate enthusiasts, Turkey Cr Watershed Site 40 serves as a valuable asset in the local ecosystem, providing essential services for fire protection, water storage, and environmental conservation. Its strategic location in Wiota, Iowa, under the representation of Congresswoman Cindy Axne, highlights the collaborative efforts between local and federal agencies to safeguard water resources and mitigate potential risks in the region.

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.
