Summary
Built in 1957, this earth dam stands at a height of 32 feet and has a length of 499 feet, with a storage capacity of 102 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, with a low hazard potential rating. Despite its age, the dam's condition has not been rated, highlighting the need for further assessment and potentially, maintenance.
The dam's primary purpose and associated structures are not specified in the data, but its location in a state-regulated jurisdiction underscores the importance of proper management and upkeep. With a maximum discharge of 360 cubic feet per second, the dam plays a crucial role in water resource management in the region. The absence of emergency action plans and inundation maps, however, raises concerns about the readiness for potential risks and the need for comprehensive risk assessment and management measures to ensure the safety and integrity of Carr #4 for the surrounding community and environment.
As a key structure in the St. Paul District and with oversight from the DENR, Carr #4 serves as a vital component in the local water infrastructure. With its low hazard potential and lack of recent condition assessment, there is a clear opportunity for stakeholders to prioritize the evaluation and maintenance of this dam to enhance its resilience in the face of changing climate conditions and potential emergencies. Collaboration between private owners, regulatory agencies, and the community will be essential in safeguarding the long-term sustainability and functionality of Carr #4 for the benefit of all involved.

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.
