Summary
With a height of 16 feet and a length of 480 feet, this structure serves a vital role in regulating the flow of the TR-Moreau River. Managed by the South Dakota Department of Environment and Natural Resources (DENR), Louie Englehardt is state-regulated and undergoes regular inspections, permitting, and enforcement to ensure its functionality and safety.
Despite its low hazard potential and a condition assessment that is currently not rated, Louie Englehardt remains a crucial component of the local water resource management system. With a storage capacity of 77 acre-feet and a normal storage level of 54 acre-feet, this dam helps to control the flow of the TR-Moreau River and mitigate potential flooding risks in the surrounding area. The dam also has a maximum discharge capacity of 400 cubic feet per second, further highlighting its importance in managing water resources in South Dakota.
Louie Englehardt represents a collaboration between private ownership and federal agencies like the Natural Resources Conservation Service. While its Emergency Action Plan status and risk assessment details are currently unlisted, the dam's strategic location and design contribute significantly to the overall water resource management efforts in the region. For water resource and climate enthusiasts, Louie Englehardt serves as a tangible example of how infrastructure can play a crucial role in maintaining ecological balance and safeguarding communities from potential water-related hazards.

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.
