Summary

This earth dam stands at 25 feet tall and spans 800 feet, serving the primary purpose of water retention in the Brule Creek tributary. With a capacity to store 207 acre-feet of water, the dam plays a vital role in regulating the flow of the stream, with a maximum discharge capacity of 1632 cubic feet per second.

Managed by the local government and regulated by the South Dakota Department of Agriculture and Natural Resources, Brule Creek Watershed Dt Dam B-16 has been deemed to have a low hazard potential. Despite not being rated in terms of condition assessment, the dam has not undergone any modifications since its construction. While the last inspection dates back to 1981, the dam is equipped with emergency preparedness measures, although details on emergency action plans and risk assessments are currently unavailable. As an essential component of the water infrastructure in the region, ongoing monitoring and maintenance are necessary to ensure the structural integrity and operational efficiency of Brule Creek Watershed Dt Dam B-16.

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.
