Summary
The earth dam, completed in 1972, stands at 34 feet high and spans 693 feet in length, with a storage capacity of 109 acre-feet. Situated along the TR-LONE TREE BRANCH river/stream, this site plays a crucial role in managing water resources in the area.
Managed by the Iowa DNR, Turkey Cr Watershed Site 19-21 is state-regulated and permitted, with inspections and enforcement in place for safety and compliance. The dam has a low hazard potential and is currently in a not rated condition assessment status. Despite its moderate risk level, the site's risk management measures and emergency preparedness plans are not specified, leaving room for improvement in ensuring the safety and integrity of the structure. With its strategic location and purpose, this site serves as a key component in water resource management and climate resilience efforts in the region.
Overall, Turkey Cr Watershed Site 19-21 is a vital infrastructure for water management and environmental protection in the area. With its multiple purposes and regulatory oversight, this earth dam plays a significant role in flood risk reduction and maintaining water quality in the TR-LONE TREE BRANCH. As climate change impacts continue to pose challenges, the proper maintenance and risk management of this site are essential for ensuring the safety and well-being of the surrounding community and ecosystem.

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.
