Summary
Built in 1954 by the Natural Resources Conservation Service, this dam stands at a height of 27 feet and has a length of 351 feet. With a storage capacity of 61 acre-feet, it serves as a crucial water resource for the surrounding area, providing irrigation and flood control benefits to the local community.
Despite its age, Dykstra Number 13 is classified as having a low hazard potential, indicating a relatively low risk of failure. While its condition assessment is currently listed as "Not Rated," the dam is regulated by the South Dakota Department of Environment and Natural Resources, ensuring that it is inspected, permitted, and enforced to meet safety standards. With a maximum discharge capacity of 375 cubic feet per second, this dam plays a vital role in managing water flow in the region.
As a key component of the water infrastructure in South Dakota, Dykstra Number 13 underscores the importance of maintaining and regulating dams to ensure the safety and sustainability of water resources in the face of changing climate conditions. With its historical significance and ongoing role in water management, this dam serves as a reminder of the interconnected relationship between water resources, climate resilience, and community well-being.

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.
