Summary
Built in 1972 by the USDA NRCS, this dam stands at a height of 44 feet and has a storage capacity of 470 acre-feet. With a low hazard potential, the dam serves as a vital resource for water management in the region, with a normal storage capacity of 80 acre-feet and a maximum discharge rate of 1650 cubic feet per second.
Situated in the Omaha District, the Mud Creek Dt Dam M-1 is regulated by the South Dakota Department of Environment and Natural Resources (DENR), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations. The dam plays a crucial role in flood control and water supply management in the area, demonstrating a commitment to sustainable water resource management. Despite being structurally sound and not yet rated for condition assessment, the dam continues to serve its purpose effectively.
For water resource and climate enthusiasts, the Mud Creek Dt Dam M-1 is a noteworthy structure that highlights the importance of earth dams in water management systems. With its strategic location, design by USDA NRCS, and state regulation, this dam is a key component of the region's infrastructure. As climate change continues to impact water resources, the Mud Creek Dt Dam M-1 stands as a testament to the ongoing efforts to protect and manage water sources for the community's benefit.

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.
