Summary
Managed by the state regulatory agency MNDNR EWR, this Earth dam structure stands at a height of 9 feet and has a storage capacity of 440 acre-feet. The dam's low hazard potential and satisfactory condition assessment make it a crucial asset for water resource management in the region.
With a drainage area of 4.5 square miles and a maximum discharge of 50 cubic feet per second, Mud Lake Restoration provides essential flood control and habitat enhancement for local wildlife. The project's location along Cottonwood Creek-TR and its close proximity to the city of Dassel highlight its significance in preserving water quality and supporting biodiversity in the area. As part of ongoing inspection and enforcement efforts by the state, the dam continues to play a vital role in maintaining a balanced ecosystem and ensuring the safety of nearby communities.
As climate change impacts water resources, the Mud Lake Restoration project serves as a model for sustainable water management practices. Through collaboration between state agencies and designers from NRCS, this initiative showcases the importance of maintaining and enhancing natural habitats while addressing the challenges posed by a changing climate. By prioritizing the conservation of water resources and promoting ecological resilience, Mud Lake Restoration stands as a testament to the proactive efforts being taken to safeguard our environment for future generations.

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.
