Summary
This earth dam, constructed in 1972 by the USDA NRCS, stands at a height of 28 feet and has a storage capacity of 70 acre-feet. With a low hazard potential and moderate risk assessment, this dam plays a crucial role in flood risk reduction and water management in the Turkey Creek watershed.
Managed by the Iowa Department of Natural Resources, this dam on TR-Bear Creek is regulated, permitted, inspected, and enforced to ensure its structural integrity and compliance with state regulations. The dam, with a drainage area of 0.19 square miles and a surface area of 6 acres, serves as a critical component of the local water infrastructure. The surrounding area, including the city of Lewis, benefits from the water management practices implemented at this site, safeguarding the community from potential hazards and contributing to sustainable water resource management.
As an essential structure in the Omaha District, Turkey Cr Watershed Site 10-8 not only provides valuable water resource benefits but also highlights the importance of collaborative efforts between local governments, federal agencies, and environmental conservation organizations. With its strategic location and functional design, this dam exemplifies the intersection of water resource management, climate resilience, and community safety in the region, underscoring the significance of proactive measures in safeguarding our natural resources 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.
