Summary
Brule Creek. Built in 1966, this earth dam stands at a height of 29 feet and has a storage capacity of 376 acre-feet, with a normal storage capacity of 189 acre-feet. The dam spans 674 feet in length and has a maximum discharge capacity of 2178 cubic feet per second.
Managed by the local government and regulated by the South Dakota Department of Environment and Natural Resources (DENR), Brule Creek Watershed Dt Dam B-26 has a low hazard potential and is currently rated as 'Not Rated' in terms of condition assessment. While the dam has not been inspected recently, it is equipped with state permitting, inspection, and enforcement mechanisms to ensure its safe operation. Although there is no Emergency Action Plan (EAP) in place, the dam has not been identified to pose significant risks, and no risk management measures have been implemented.
Overall, Brule Creek Watershed Dt Dam B-26 plays a crucial role in water resource management in the region, providing flood control and water storage capabilities. With its strategic location and design by the USDA NRCS, the dam serves as a key infrastructure for climate and water enthusiasts interested in the conservation and regulation of water resources in the Brule Creek watershed.

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.
