Summary
Completed in 1997, this earth dam stands at a height of 31 feet with a length of 534 feet, providing a storage capacity of 118 acre-feet. Situated on the TR-Grand River, Peters Dam plays a crucial role in managing water resources in the area, with a surface area of 8.3 acres and a drainage area of 0.24 square miles.
Despite its low hazard potential, Peters Dam is regulated by the Iowa Department of Natural Resources and undergoes regular inspections to ensure its structural integrity. The dam features an uncontrolled spillway type and has not been modified since its completion. With a moderate risk assessment score of 3, Peters Dam is equipped with appropriate risk management measures to mitigate any potential threats. Although the condition assessment is currently rated as "Not Rated", the dam serves as a vital infrastructure for water resource management and climate resilience efforts in the region.
Overall, Peters Dam stands as a testament to effective water resource management and climate adaptation strategies in Iowa. With its primary purpose of providing essential services for fire protection and agriculture, this privately owned earth dam serves as a valuable asset in safeguarding the community against water-related risks. As climate change continues to impact the frequency and intensity of extreme weather events, structures like Peters Dam play a crucial role in ensuring the sustainability and resilience of water resources in the face of evolving environmental challenges.

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.
