Summary
Completed in 1952, this dam serves a primary purpose that is not specified, with a storage capacity of 52 acre-feet and a maximum discharge of 600 cubic feet per second. Despite being rated as having a low hazard potential, the condition assessment for Wesley Beaman is currently listed as "Not Rated," indicating a need for further evaluation.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Wesley Beaman is regulated, permitted, inspected, and enforced upon by state authorities. The dam falls under the jurisdiction of the St. Paul District of the US Army Corps of Engineers, positioning it within a network of water resource management agencies. With its location along the TR MISSONot RatedI river or stream, Wesley Beaman stands as a significant structure contributing to water resource management in the region, yet details about its primary purpose and associated structures remain unspecified.
Although the specifics of emergency preparedness, risk assessment, and management measures are currently not available for Wesley Beaman, its presence as an earth dam with state oversight highlights its importance in water resource and climate resilience efforts. As a water resource and climate enthusiast, the unique characteristics and regulatory framework surrounding Wesley Beaman present an intriguing case study for understanding the intricate balance between water management, infrastructure maintenance, and environmental protection in South Dakota.

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.
