Summary
Completed in 1978, this earth dam stands at a height of 34 feet and has a length of 1020 feet, providing a storage capacity of 104 acre-feet. The dam serves multiple functions including flood risk reduction, with a drainage area of 0.27 square miles.
Managed by the Iowa Department of Natural Resources, Turkey Cr Watershed Site 47 is regulated, inspected, and enforced by the state agency to ensure its safety and compliance with regulations. Despite being classified as having a low hazard potential, the dam is rated as not assessed for its condition. With a moderate risk assessment score of 3, there is a need for continued monitoring and risk management measures to mitigate any potential issues and ensure the safety of the surrounding community.
Although the dam has not been modified in recent years and lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP), it remains a vital structure for the local area, serving as an essential water resource for fire protection and other purposes. As water resource and climate enthusiasts, it is crucial to monitor and support the maintenance and management of dams like Turkey Cr Watershed Site 47 to safeguard our water supply and infrastructure against potential risks and ensure sustainable water management practices.

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.
