The primary purpose of this dam is for fire protection, stock, and small fish pond usage, as well as flood risk reduction in the area.
Managed by the Iowa DNR, this dam on TR-WRIGHT CREEK is state-regulated and undergoes regular inspections to ensure public safety. With a low hazard potential and a moderate risk assessment rating of 3, the condition of Bruene-Spahn Subwtrshd Sta 32+82 #6 is currently not rated. While the emergency action plan status is unknown, the structure meets state permitting and enforcement requirements, demonstrating a commitment to effective risk management and water resource protection in the region.
Overall, Bruene-Spahn Subwtrshd Sta 32+82 #6 plays a crucial role in safeguarding the local community and environment against potential flooding and ensuring a sustainable water supply for various purposes. As a key component of the water infrastructure in the area, this dam serves as a testament to the collaborative efforts of local government agencies and the USDA NRCS in managing and maintaining water resources in Iowa.

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.
