Summary
This dam serves multiple purposes including fire protection, stock, small fish pond management, and flood risk reduction, with a primary height of 33 feet and a length of 976 feet. With a storage capacity of 228 acre-feet and a drainage area of 1.36 square miles, this structure plays a crucial role in managing water resources in the area.
Managed by the Iowa Department of Natural Resources, the Turkey Cr Watershed Site 40-5a is regulated, permitted, inspected, and enforced by state authorities. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk level, this dam contributes to the overall water management strategy in the region and provides essential support for various water-related activities.
Situated near the TR-Turkey Creek, this dam is an integral part of the local water infrastructure, ensuring water availability for fire protection, agriculture, and environmental purposes. With its strategic location and multi-purpose design, the Turkey Cr Watershed Site 40-5a stands as a significant asset in the ongoing efforts to manage water resources and mitigate climate-related risks in the area.

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.
