Summary
Completed in 2005, this Earth-type dam stands at a height of 31 feet and has a length of 820 feet, with a storage capacity of 316 acre-feet. The dam is located on the TR-Lone Tree Branch river and is regulated by the Iowa DNR, with state permitting, inspection, and enforcement in place to ensure its safety and functionality.
With a low hazard potential and a moderate risk assessment rating, Turkey Creek Watershed Site 10-26 plays a crucial role in mitigating flood risks in the area. The dam's uncontrolled spillway and soil foundation contribute to its effectiveness in managing water levels and protecting the surrounding community from potential disasters. Although the dam's condition assessment is currently listed as 'Not Rated', the state-regulated inspections and enforcement mechanisms ensure that any necessary maintenance or repairs are promptly addressed to maintain the dam's integrity and safety standards.
For water resource and climate enthusiasts, Turkey Creek Watershed Site 10-26 serves as a noteworthy example of local government-led flood risk reduction efforts in Iowa. The dam's strategic location, design specifications, and state-regulated oversight highlight the importance of proactive infrastructure investments in safeguarding communities against the impacts of extreme weather events. As climate change continues to pose challenges for water management, the role of structures like Turkey Creek Watershed Site 10-26 becomes increasingly vital in enhancing resilience and adaptation to evolving environmental conditions.

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.
