Summary
The dam, with a height of 31 feet and a length of 640 feet, serves multiple purposes including fire protection, stock watering, and small fish pond maintenance. With a storage capacity of 226 acre-feet and a drainage area of 1.07 square miles, the dam plays a critical role in flood risk reduction in the area.
Managed by the Iowa DNR, this dam on Turkey Creek is regulated, permitted, inspected, and enforced by the state to ensure its safety and functionality. The dam's condition was assessed as fair in 2015, with a significant hazard potential. Despite its moderate risk level, the dam has not been modified in recent years, and its emergency action plan and inundation maps are yet to be prepared. The site is in the jurisdiction of Representative Cindy Axne and is situated in the Omaha District.
Overall, Turkey Cr Watershed Site 24-1 is a vital infrastructure for water resource management in the region, providing essential services for fire protection, stock watering, and flood risk reduction. As climate change continues to impact water resources, it is crucial to ensure the proper maintenance and monitoring of such structures to safeguard communities and ecosystems. The dam's condition assessment and risk management measures highlight the importance of ongoing oversight and preparedness to mitigate potential hazards and ensure the resilience of the watershed system.

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.
