Summary

Completed in 2004, this earth dam stands at a height of 26 feet and spans 750 feet in length. With a storage capacity of 77 acre-feet, it serves to control the flow of water in the area, with a maximum discharge of 551 cubic feet per second.

Owned privately, Brehmer Dam is regulated by the Iowa DNR and is subject to state inspections and enforcement. Although classified as having a low hazard potential, the dam is considered to have a moderate risk level according to a risk assessment, highlighting the importance of proper management and maintenance. Despite not having a condition assessment rating, the dam plays a crucial role in managing water resources in the region and minimizing the risk of flooding.

Situated in Pottawattamie County, Brehmer Dam not only serves as a structure for grade stabilization but also contributes to the overall management of water resources in the area. Its strategic location on TR-Indian Creek ensures the protection of surrounding areas from potential flooding, showcasing the vital role that dams play in climate resilience and water conservation efforts. With its moderate risk level and state-regulated status, Brehmer Dam stands as a testament to the importance of proper infrastructure in safeguarding against the impacts of climate change on water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
