Summary
This earth dam stands at 26 feet high and spans 352 feet in length, with a storage capacity of 41 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
With a low hazard potential and a condition assessment of "Not Rated", Bleha Dam plays a crucial role in water resource management in the area. It is designed to control the flow of the TR-MISSONot RatedI river or stream and has a maximum discharge capacity of 660 cubic feet per second. Despite not having a specified primary purpose, the dam serves as a vital infrastructure for flood control, irrigation, and water supply for the surrounding community.
Located within the St. Paul District of the US Army Corps of Engineers, Bleha Dam contributes to the overall water resource management efforts in the region. Its existence ensures the safety and stability of the local ecosystem, while also supporting various water-related activities. As a key player in the state's water infrastructure, Bleha Dam stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns and increasing water demands.

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.
