Summary
Owned by the local government and regulated by the Iowa Department of Natural Resources, this earth dam was completed in 1980 by the USDA NRCS and serves multiple purposes including fire protection, stock, and small fish pond management. With a dam height of 36 feet and a storage capacity of 310 acre-feet, this structure plays a vital role in mitigating potential flooding events in the area.
Located in the city of Anita, Turkey Creek Watershed Site 59-D-2 covers a drainage area of 0.91 square miles and has a surface area of 13.6 acres. The dam, constructed with stone core and soil foundation, has a spillway type of uncontrolled and a spillway width of 2 feet. Despite a fair condition assessment as of June 2019, this dam has a significant hazard potential and is inspected every five years to ensure its structural integrity and functionality in the face of potential emergencies.
With a moderate risk assessment score of 3, Turkey Creek Watershed Site 59-D-2 is a key element in the water resource management strategy of the region. As part of the flood risk reduction infrastructure, this dam provides essential protection to the surrounding areas and contributes to the overall resilience of the watershed. Managed by the local government and designed by the USDA NRCS, this site stands as a testament to the collaborative efforts in safeguarding water resources and addressing the challenges posed by climate variability in the region.

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.
