Summary
With a height of 22 feet and a length of 1030 feet, the dam has a storage capacity of 340 acre-feet and a maximum discharge of 3400 cfs. Situated on a tributary of Indian Creek, the dam is regulated by the South Dakota Department of Environment and Natural Resources and is inspected, permitted, and enforced by state agencies.
Despite its low hazard potential, Royal Mcknight Dam No.2 plays a crucial role in water resource management in the region, providing irrigation water for agricultural activities and helping to regulate stream flow in the area. The dam's condition is currently not rated, and its Emergency Action Plan (EAP) status and risk assessment are not available. Although the dam has not been modified in recent years, it remains an essential piece of infrastructure for the community it serves.
Water resource and climate enthusiasts will find Royal Mcknight Dam No.2 a fascinating example of how private ownership, state regulation, and federal agency involvement intersect in the management of water infrastructure. With its strategic location and vital role in water storage and discharge, the dam represents a key component of the region's water resource system and highlights the importance of proper maintenance and oversight to ensure its continued functionality and safety.

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.
