Summary
Constructed in 1963 by the Natural Resources Conservation Service, this dam stands at a height of 25 feet and has a storage capacity of 41 acre-feet. Despite its low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources, with regular inspections and enforcement to ensure its safety and functionality.
The dam's primary purpose and associated structures are not specified, but it serves as a vital resource for water management in the region. With a maximum discharge of 937 cubic feet per second, Hight Number 1 plays a crucial role in flood control and water supply for the surrounding area. As a key component of the local water infrastructure, this dam contributes to the overall resilience of the ecosystem and helps mitigate the impacts of climate change on water resources in the region.
Although the condition assessment of Hight Number 1 is currently listed as "Not Rated," the dam's low hazard potential and state jurisdiction indicate that it is well-maintained and poses minimal risk to the community. With a history of successful operations and regulatory oversight, this earth dam exemplifies the importance of proactive management and collaboration between private owners and state agencies to ensure the sustainability of water resources in South Dakota.

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.
