Summary
Built in 1958, this Earth-type dam serves the primary purpose of water storage along the TR-BAD River, with a maximum storage capacity of 232 acre-feet and a normal storage level of 104 acre-feet. The dam has a height of 16 feet and a length of 600 feet, providing essential flood control and water supply benefits to the surrounding area.
Managed by the Natural Resources Conservation Service, Pere Pearson is regulated by the South Dakota Department of Environment and Natural Resources, ensuring its safety and compliance with state regulations. Despite being classified as having a low hazard potential, the dam's condition assessment is currently listed as "Not Rated," highlighting the need for ongoing monitoring and maintenance to uphold its structural integrity. With a maximum discharge capacity of 900 cubic feet per second, Pere Pearson plays a crucial role in mitigating flood risks and supporting water sustainability efforts in the region.
As climate change continues to impact water resources, structures like Pere Pearson serve as vital components in our efforts to adapt and mitigate environmental challenges. With its strategic location and operational capabilities, Pere Pearson stands as a symbol of resilience and proactive stewardship in the face of evolving climate patterns. As enthusiasts in water resource and climate conservation, understanding and supporting the maintenance of dams like Pere Pearson is essential in ensuring a sustainable future for our communities and ecosystems.

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.
