Summary
Lake No.2, located in Potter, South Dakota, is a privately owned earth dam with a height of 26 feet and a length of 316 feet. Completed in 1948, this dam has a storage capacity of 73 acre-feet and a maximum discharge of 208 cubic feet per second. Despite being classified as low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement processes in place to ensure its safety and compliance with regulations.
Managed by the Natural Resources Conservation Service, Jay A. Lake No.2 serves a crucial role in water resource management in the region. The dam helps control water flow in the TR-MISSONot RatedI river or stream, providing essential water storage for agricultural and environmental purposes. While the dam's condition assessment is currently listed as "Not Rated," its low hazard potential suggests that it poses minimal risk to surrounding areas. Emergency action plans and risk management measures are likely in place to address any potential issues that may arise.
As a key component of the St. Paul District in South Dakota, Jay A. Lake No.2 plays a vital role in maintaining water quality, supporting irrigation, and safeguarding against floods in the area. With a focus on sustainability and environmental stewardship, the dam serves as a critical infrastructure for water resource and climate enthusiasts who are passionate about preserving and protecting our natural resources for future generations.

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.
