Summary
Constructed in 1950, this earth dam stands at a height of 25 feet and has a storage capacity of 63 acre-feet. With a maximum discharge capacity of 198 cubic feet per second, the dam serves the primary purpose of controlling water flow and providing water storage for the surrounding area.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Volberg #2 is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and compliance with regulations. Despite being rated as having a low hazard potential and not yet assessed for condition, the dam plays a crucial role in water resource management and climate resilience efforts in the region. As a key piece of infrastructure, Volberg #2 serves as a vital resource for water supply and flood control in the area.
Although there are no associated structures or emergency action plans in place for Volberg #2, its strategic location and design make it an essential component of the local water management system. As climate change continues to impact water resources, dams like Volberg #2 will play a critical role in adapting to changing conditions and ensuring the sustainable use of water for the community. With proper monitoring and maintenance, Volberg #2 will continue to serve as a valuable asset for water resource and climate enthusiasts in South Dakota.

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.
