Summary
The dam, completed in 1974, stands at a height of 31 feet and spans a length of 600 feet, with a storage capacity of 109 acre-feet. Despite its relatively low hazard potential, the site plays a crucial role in flood risk reduction within the TR-Lone Tree Branch of Turkey Creek.
Managed by the USDA NRCS, this earth dam serves as a key component in the region's water management infrastructure, with a drainage area of 0.39 square miles and a surface area of 6.4 acres. While the dam's condition assessment is currently not rated, its risk assessment indicates a moderate level of risk. The dam's regulatory oversight and enforcement by the Iowa DNR, along with its state permitting and inspection processes, ensure its continued functionality and safety for the surrounding community.
As climate change exacerbates water resource challenges, Turkey Cr Watershed Site 10-24 stands as a critical asset in mitigating flood risks and maintaining water security in the region. With its strategic location in the Turkey Creek watershed and its multifaceted purposes, this site exemplifies the importance of sustainable water management practices in the face of evolving climatic conditions.

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.
