Summary
Built in 1977 by the Natural Resources Conservation Service, this dam stands at a height of 31 feet and has a storage capacity of 72 acre-feet. With a low hazard potential and a condition assessment of "Not Rated," Peters #1 is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it meets state permitting, inspection, and enforcement standards.
Situated in a rural area with no associated structures, Peters #1 serves a primary purpose that is not specified in the data. The dam has a maximum discharge capacity of 1421 cubic feet per second and a normal storage level of 52 acre-feet. Despite lacking certain details such as surface area and drainage area, Peters #1 remains in compliance with state jurisdiction and regulatory agency requirements, giving confidence to water resource and climate enthusiasts that this structure is being properly managed and monitored for any potential risks or emergencies.
With its location in a sparsely populated region and a history of low hazard potential, Peters #1 stands as a testament to responsible dam ownership and maintenance. While additional details about the dam's purposes and usage may be needed for a complete understanding, its adherence to state regulations and inspection requirements provides assurance to those interested in water resource management and climate adaptation efforts in the region.

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.
