Summary
Built in 1940, this earth-type dam stands at a height of 14 feet and spans 600 feet, with a storage capacity of 102 acre-feet. Despite its age, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources (DENR), ensuring its safety and compliance with state regulations.
The dam poses a low hazard potential and has not been rated for condition assessment, indicating a stable and maintained structure. While details on emergency action plans and risk management measures are not available, the presence of state-permitting, inspection, and enforcement processes suggest a commitment to safety and environmental compliance. With a maximum discharge capacity of 1450 cubic feet per second, Dave Peterson No.4 plays a crucial role in managing water resources and mitigating potential flood risks in the region.
Managed by a private owner, this dam serves as a key infrastructure for water resource management in the area, with its design and construction overseen by state regulatory agencies. As a significant structure along the TR-Bad River, Dave Peterson No.4 stands as a testament to the importance of maintaining and monitoring our water resources in the face of changing climate patterns. Climate and water resource enthusiasts will find this dam a fascinating example of the intersection between human infrastructure and environmental stewardship.

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.
