Summary
Keffeler is a privately owned earth dam located in Meade, South Dakota, along the TR CHEYENNE river. This dam, completed in 1948, stands at 14 feet in height and has a storage capacity of 77 acre-feet. With a low hazard potential and a condition assessment of "Not Rated", D. Keffeler plays a crucial role in water resource management in the region.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), D. Keffeler is regulated, permitted, inspected, and enforced by the state. While the dam has not been modified in recent years, it serves as a valuable infrastructure for flood control and water supply. With a maximum discharge capacity of 12,000 cubic feet per second, this dam is equipped to handle high water levels during extreme weather events.
Although D. Keffeler has not been assigned a Dam Safety Action Classification (DSAC) date or undergone a risk assessment, it remains an essential component of the local water management system. Water resource and climate enthusiasts can appreciate the role of D. Keffeler in maintaining water quality, managing water flow, and safeguarding against potential hazards in the region.

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.
