Summary
3, located in Twin Valley, Minnesota, is a vital structure designed by USDA NRCS to reduce flood risks along the Wild Rice River. Completed in 1977, this earth dam stands at a height of 32 feet with a structural height of 35 feet, providing a maximum storage capacity of 460 acre-feet. Despite its low hazard potential and fair condition assessment, the dam is regulated and inspected by the Minnesota Department of Natural Resources, ensuring its safety and functionality for the surrounding community.
With a drainage area of 12 square miles, Mashaug Creek Dam No. 3 plays a crucial role in managing water flow and mitigating potential risks in the region. Its uncontrolled spillway type and gates indicate a simple yet effective design for flood control purposes. The dam's association with the Wild Rice River and its moderate risk assessment highlight the importance of maintaining and monitoring this structure to safeguard both the environment and local residents from potential water-related disasters.
As water resource and climate enthusiasts, understanding the significance of Mashaug Creek Dam No. 3 in flood risk reduction and water management efforts is essential. Its construction by the Natural Resources Conservation Service and ongoing regulatory oversight by the MNDNR EWR demonstrate a commitment to sustainable infrastructure practices for the benefit of the community. By staying informed about the dam's condition, inspection dates, and risk management measures, enthusiasts can contribute to the preservation and resilience of water resources in Norman County, Minnesota.

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.
