Summary
Completed in 1951, this earth dam stands at a height of 22 feet and has a storage capacity of 123 acre-feet, with a normal storage level of 106 acre-feet. The dam is situated on the TR-Grand River, under the jurisdiction of the South Dakota Department of Environment and Natural Resources (DENR).
Despite its low hazard potential, the North Dam is regulated and inspected by state authorities to ensure its safety and functionality. With a maximum discharge capacity of 600 cubic feet per second, the dam plays a crucial role in flood control and water management for the region. The condition assessment of the dam is currently not rated, indicating a need for further evaluation and maintenance to uphold its integrity.
As an essential part of the local water infrastructure, the North Dam provides a reliable source of water storage and management for the surrounding community. With its strategic location and design, the dam continues to play a significant role in ensuring water security and resilience in the face of changing climate conditions. Climate and water resource enthusiasts can appreciate the importance of the North Dam in safeguarding the region's water supply and mitigating potential risks associated with water management.

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.
