Summary
This structure, located on the TR-JIM BRANCH river or stream, has a dam height of 22 feet, a length of 600 feet, and a storage capacity of 112 acre-feet. With a surface area of 7.1 acres and a drainage area of 0.22 square miles, this dam serves multiple functions including flood risk reduction.
Managed by the Iowa DNR, Turkey Cr Watershed Site 19-34a has a low hazard potential and a moderate risk rating, indicating the need for ongoing monitoring and risk management measures. While the dam's condition is currently not rated, it undergoes state inspection, permitting, and enforcement to ensure its structural integrity and functionality. The dam's purpose, design, and location make it a crucial asset for water resource management and climate resilience in the region, providing essential services for the local community and ecosystem.
As part of the Omaha District's water infrastructure, this dam plays a significant role in water storage, flow regulation, and environmental protection. With its association with fire protection, stock watering, and flood risk reduction, Turkey Cr Watershed Site 19-34a serves as a vital resource for sustaining water availability and quality in the area. Its construction and maintenance by the Natural Resources Conservation Service underscore the importance of collaborative efforts in managing water resources and adapting to the changing climate conditions for a more sustainable future.

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.
