Summary
The dam, standing at a height of 32 feet and stretching 615 feet in length, serves multiple purposes including fire protection, stock maintenance, and small fish pond creation. With a storage capacity of 50 acre-feet and a drainage area of 0.25 square miles, this structure plays a crucial role in flood risk reduction in the area.
Managed by the Iowa Department of Natural Resources, the Turkey Cr Watershed Site 40-2 has a low hazard potential and a moderate risk rating. Despite being uncontrolled, the spillway type of the dam ensures proper water management during high flow events. Although the condition of the dam has not been rated recently, its historical significance in the region's water resource management cannot be overlooked. With its remote location in Wiota, Iowa, this dam serves as a key asset for the community's water infrastructure and environmental conservation efforts.
For water resource and climate enthusiasts, the Turkey Cr Watershed Site 40-2 represents a harmonious blend of human engineering and natural resource management. As a vital component of the local ecosystem, this dam not only provides essential services like fire protection and flood risk reduction but also creates a habitat for aquatic life. With its strategic location along the Turkey Creek, this structure showcases the importance of sustainable water management practices in safeguarding the environment for future generations.

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.
