Marsh Creek 3, located in the city of Twin Valley, Minnesota, is a local government-owned dam that plays a vital role in flood risk reduction along the Marsh Creek-TR river. 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.
