Summary
Bachand, a privately owned dam located in Meade, South Dakota, stands as a crucial water resource management structure along the TR Cheyenne river. Built in 1943, this earth dam has a height of 23 feet and a length of 680 feet, providing a storage capacity of 139 acre-feet with a maximum discharge of 4000 cubic feet per second. Despite its age, the dam is considered to have a low hazard potential and is currently not rated in terms of its condition assessment.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), L. Bachand is subject to state regulations, permitting, inspection, and enforcement to ensure its safe operation. The dam's primary purpose and associated structures are not specified, but its significance in flood control and water storage for the surrounding area cannot be understated. While the dam has not undergone recent inspection or maintenance assessments, its overall risk assessment and management measures remain undisclosed.
In the realm of water resource and climate management, L. Bachand serves as a valuable asset in South Dakota's infrastructure, contributing to flood mitigation efforts and water supply reliability. As water resource enthusiasts, understanding the operational and regulatory aspects of dams like L. Bachand is essential for ensuring the sustainable management of our natural resources in the face of changing climate conditions.

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.
