Summary
The earth dam stands at a height of 24 feet and was completed in 1945, providing a storage capacity of 96 acre-feet. With a low hazard potential and a condition assessment that is not rated, this dam serves primarily as a water resource structure in the region.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Pfister Pond #1 is subject to state regulations for permitting, inspection, and enforcement. While the dam has not been assessed for its emergency action plan preparedness or risk management measures, it remains a vital component of the local water infrastructure. With a maximum discharge capacity of 2200 cubic feet per second, this dam plays a crucial role in flood control and water management in the area.
Despite its age, Pfister Pond #1 continues to serve its purpose effectively, with a solid construction and storage capacity for water resource management. As climate change and water scarcity concerns grow, dams like Pfister Pond #1 will play an increasingly important role in ensuring the sustainable use and conservation of water resources 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.
