Summary
Constructed in 1956 by the Natural Resources Conservation Service, this dam stands at a height of 28 feet and has a length of 390 feet, providing a maximum storage capacity of 22 acre-feet. Despite being classified with a low hazard potential, the dam is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources.
With a primary purpose not specified, Dalhke Ranch Number 5 serves as a vital infrastructure for water resource management in the region. Its normal storage capacity of 15 acre-feet plays a crucial role in regulating the flow of the White River and ensuring water availability for agricultural and environmental purposes. The dam's proximity to St. Paul District of the US Army Corps of Engineers and the oversight by the state regulatory agency underlines its significance in maintaining water security and mitigating flood risks in the area.
While the condition of Dalhke Ranch Number 5 is currently not rated, its presence as a regulated and inspected structure highlights its importance in the overall water resource management strategy of South Dakota. With its low hazard potential and historical significance in water storage and flow regulation, this dam stands as a testament to the collaborative efforts between private landowners, government agencies, and conservation services in safeguarding water resources and enhancing climate resilience 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.
