Summary
Weyers, located in Meade, South Dakota, is a privately owned earth dam completed in 1954 with a height of 23 feet and a storage capacity of 230 acre-feet. Situated on the TR CHEYENNE river within the St. Paul District, this dam serves as a vital water resource infrastructure in the region. Despite being classified as a low hazard potential structure with a condition assessment of "Not Rated", it is regulated by the South Dakota Department of Environment and Natural Resources, ensuring state permitting, inspection, and enforcement protocols are in place.
Managed by the Natural Resources Conservation Service, M. Weyers plays a crucial role in water management and conservation efforts in South Dakota. While the dam lacks a comprehensive risk assessment and emergency action plan, it remains a key component of the local water infrastructure. With a normal storage capacity of 114 acre-feet and a maximum discharge of 1800 cubic feet per second, M. Weyers contributes to flood control and water supply needs in the region.
As a significant feature in the water resource landscape, M. Weyers stands as a testament to the importance of sustainable water management practices. Although its condition assessment is currently "Not Rated" and lacks certain emergency preparedness measures, the dam continues to provide essential water storage and control functions. With its historical significance dating back to 1954, M. Weyers remains a valuable asset in safeguarding the water resources of Meade, South Dakota, and beyond.

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.
