Summary
Completed in 1955, the dam stands at a height of 25 feet and has a storage capacity of 41 acre-feet. It is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
Situated on a tributary of Pine Creek, Carr #5 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam has not been modified in recent years, and information on emergency action plans, inundation maps, and risk management measures is not provided in the dataset. With a maximum discharge capacity of 269 cubic feet per second, Carr #5 plays a role in managing water resources in the area and contributes to the overall hydrological system in South Dakota.
Despite its relatively small size and low hazard potential, Carr #5 serves as an important infrastructure for water resource management in the region. The dam's presence on a tributary of Pine Creek highlights its significance in the local watershed and its role in regulating water flow and storage. As climate change continues to impact water resources, understanding and maintaining structures like Carr #5 is essential for ensuring the resilience and sustainability of the region's water supply in the face of evolving environmental 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.
