Summary
Built in 1989 by Houston Eng, this earth dam stands at a height of 23 feet and spans 540 feet in length. With a storage capacity of 350 acre-feet and a drainage area of 8.6 square miles, Marsh Creek 3 serves as a crucial infrastructure for managing stormwater and mitigating potential flooding in the region.
The dam, with a significant hazard potential, has been assessed to be in satisfactory condition as of May 2009. Although the last inspection was conducted in August 2018 and the dam is regulated, permitted, and regularly inspected by the Minnesota Department of Natural Resources, there are no associated structures or federal agency involvements with Marsh Creek 3. Despite its satisfactory condition, there is a moderate risk associated with the dam, indicating the importance of continued monitoring and risk management measures to ensure the safety and effectiveness of this flood risk reduction infrastructure for the community.
With its strategic location and purposeful design, Marsh Creek 3 stands as a testament to effective water resource management and climate resilience efforts in the region. As water resource and climate enthusiasts, understanding the critical role of infrastructure like Marsh Creek 3 in safeguarding communities against flooding and ensuring sustainable water management practices is essential for promoting a more resilient and sustainable future.

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.
