Summary
Built in 1949, this Earth-type dam stands at a height of 24 feet and has a length of 375 feet, providing a storage capacity of 77 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 and a current condition assessment of "Not Rated".
Managed by the Natural Resources Conservation Service, Carl Cronin plays a crucial role in water resource management in the region, with a maximum discharge capacity of 1260 cubic feet per second. While the dam has not been rated for its condition, it is equipped with emergency action plans and meets regulatory guidelines for safety. Despite its low hazard potential, Carl Cronin remains an essential structure for water storage and flood control in the area, ensuring the protection of surrounding communities and ecosystems.
As a key component of the St. Paul District's infrastructure, Carl Cronin stands as a testament to the collaboration between private owners and state agencies in safeguarding water resources and mitigating climate-related risks. With its historical significance and continued functionality, this dam serves as a vital resource for maintaining water security and resilience in the face of changing environmental conditions 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.
