Summary
Constructed in 1955, this dam stands at 25 feet high and spans 1000 feet in length, with a storage capacity of 270 acre-feet. Despite being classified as low hazard potential, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, permitting, and enforcement to ensure its safety and compliance with state regulations.
Managed by the St. Paul District of the US Army Corps of Engineers, Donald King 2 serves a crucial role in water resource management and flood control for the surrounding area. With a maximum discharge capacity of 900 cubic feet per second, this dam plays a vital role in mitigating flood risks and safeguarding communities downstream. While the dam's condition assessment is currently listed as "Not Rated," its operational history and state regulatory oversight provide reassurance to water resource and climate enthusiasts.
In the realm of dam safety and emergency preparedness, there may be room for improvement in terms of documentation and risk management measures for Donald King 2. With no recent inspection or assessment data available, it is essential for the dam's owners and regulatory agencies to update emergency action plans, conduct risk assessments, and ensure that all safety guidelines are met. As a key infrastructure asset in the region, ongoing monitoring and proactive measures will be crucial in maintaining the integrity and resilience of Donald King 2 in the face of changing climate conditions and water resource challenges.

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.
