Lower 7 Group No. 2 is a privately owned flood risk reduction structure located in Zumbrota, Minnesota, along the TR-NO. BRANCH ZUMBRO RIVER. Built in 1971 by the USDA NRCS, this earth dam stands at 20 feet tall and spans 360 feet in length, with a maximum storage capacity of 60 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam's condition remains unrated, highlighting the need for further evaluation and maintenance to ensure its effectiveness in managing flood risks in the region.

With a spillway width of 83 feet and uncontrolled outlet gates, Lower 7 Group No. 2 plays a crucial role in mitigating floodwaters and protecting the surrounding areas from potential inundation. Its stone core and soil foundation contribute to its structural integrity, while its location within the Goodhue County landscape underscores its importance in the local water resource management system. The dam's association with the Natural Resources Conservation Service and its primary purpose of flood risk reduction emphasize the collaborative efforts involved in safeguarding communities and infrastructure from the impacts of extreme weather events.

As climate change continues to exacerbate the frequency and intensity of flooding events, the maintenance and assessment of structures like Lower 7 Group No. 2 become increasingly vital in ensuring the resilience of water resource systems. By understanding the dam's design, purpose, and risk profile, water resource and climate enthusiasts can appreciate the intricate balance between human intervention and natural forces in managing water-related hazards. As such, ongoing monitoring and maintenance efforts will be essential in safeguarding the dam's effectiveness and protecting the local community from the impacts of future flood events.
