Summary
Built in 1950 and managed by the Natural Resources Conservation Service, this earth dam spans 326 feet in length and has a storage capacity of 64 acre-feet. Situated on the TR-GRAND river or stream, the dam plays a crucial role in regulating water flow and storage in the area.
Despite its age, James Petik No.2 is well maintained and meets state regulatory requirements for inspection, permitting, and enforcement. With a normal storage capacity of 51 acre-feet and a maximum discharge of 536 cubic feet per second, the dam serves as an important water resource for the region. As a key piece of infrastructure in the St. Paul District managed by the federal government, the dam contributes to flood control and water management efforts in South Dakota.
Overall, James Petik No.2 stands as a testament to the importance of sustainable water resource management in the face of changing climates. Its role in mitigating flood risks and ensuring water availability underscores the need for continued monitoring and maintenance to support the region's water security. As water resource and climate enthusiasts, understanding the significance of dams like James Petik No.2 is crucial in safeguarding our natural environment and adapting to the challenges of a changing climate.

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.
