Summary
Nuzum No.2 is a privately owned earth dam constructed in 1949 on the TR CHEYENNE river. Standing at a height of 21 feet and stretching for 800 feet in length, this dam has a storage capacity of 77 acre-feet and a maximum discharge rate of 3000 cubic feet per second. Despite being classified as having a low hazard potential and not having a current condition assessment rating, the dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources (DENR).
While C. Nuzum No.2 does not have a designated primary purpose, it serves as a crucial water resource structure in the region. With state permitting, inspection, and enforcement processes in place, the dam ensures the safety and sustainability of water management in the area. The dam's emergency action plan status, risk assessment, and management measures are currently unknown, highlighting areas that may require further attention and evaluation by relevant authorities.
As part of the St. Paul District of the US Army Corps of Engineers, C. Nuzum No.2 plays a vital role in regulating water flow and storage in the region. Although lacking in some detailed information such as condition assessment and emergency preparedness, the dam's historical significance and operational capacity underscore its importance in water resource management and climate resilience efforts in South Dakota.

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.
