Summary
Lake No.3 is a privately owned dam located in Potter, South Dakota, with a low hazard potential. Built in 1952, this earth dam stands at 24 feet tall and is primarily used for water storage, with a capacity of 106 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Managed by the Natural Resources Conservation Service, Jay A. Lake No.3 plays a crucial role in water resource management in the area. With a maximum discharge capacity of 510 cubic feet per second, this dam helps regulate water flow in the TR-MISSONot RatedI river or stream. Despite its age, the dam's condition assessment is currently not rated, highlighting the importance of regular inspections and maintenance to ensure its continued functionality and safety.
As a key infrastructure for water resource and climate enthusiasts, Jay A. Lake No.3 serves as a vital component in the local water management system. Its design and construction contribute to flood control, water storage, and overall environmental sustainability in the region. With proper oversight and maintenance, this dam continues to play a crucial role in ensuring the efficient and safe utilization of water resources in South Dakota.

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.
