Summary

Reeves No.3 is a privately owned earth dam located in Meade, South Dakota, along the TR CHEYENNE river. Constructed in 1949 by the Natural Resources Conservation Service, this dam stands at a height of 23 feet and has a length of 375 feet, providing a storage capacity of 74 acre-feet. With a maximum discharge capacity of 15,000 cubic feet per second, it serves as a crucial water resource infrastructure in the region.

Despite being rated as having a low hazard potential and not yet assessed for its condition, L. Reeves No.3 plays a significant role in water management and flood control in the area. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), ensuring that it meets state inspection, permitting, and enforcement requirements. This underscores the importance of proper maintenance and oversight of water infrastructure for sustainable water resource management and climate resilience.

As a vital component of the St. Paul District's water infrastructure, L. Reeves No.3 contributes to the overall water management system in the region. Although its emergency action plan status and risk assessment details are currently unavailable, the dam's presence highlights the ongoing efforts to safeguard water resources and enhance climate adaptation measures. By understanding and monitoring the condition of such structures, water resource and climate enthusiasts can work towards ensuring the resilience and sustainability of our water infrastructure for the future.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
