Summary
Constructed in 1949, this dam stands at a height of 20 feet and has a length of 450 feet, providing a storage capacity of 124 acre-feet. With a maximum discharge of 938 cubic feet per second, the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), ensuring proper inspection, permitting, and enforcement measures are in place.
Despite being rated as having a low hazard potential and not yet assessed for condition, C Little Wounded serves as an important water resource in the region, with a normal storage capacity of 85 acre-feet. The dam plays a crucial role in regulating water flow and providing irrigation and recreational opportunities for the community. While the dam has not been modified in recent years, it is essential for water management in the area.
Managed by a private owner, C Little Wounded is a significant structure in the St. Paul District, serving as a testament to the historical water infrastructure of South Dakota. With its strategic location and contributions to water resource management, this earth dam continues to be a key asset for water enthusiasts and climate advocates in the region.

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.
