Nature-Based Solutions Case Study

Duluth 21st Avenue West Demonstration Project

State/Territory: Minnesota

The 21st Avenue West Channel Embayment of the Duluth-Superior Harbor is the site of shoreline habitat restoration. Dredged materials were placed in three locations of the embayment to restore shallow aquatic habitat, with the hopes of contributing to the delisting of the St. Louis River Estuary as an Area of Concern. This project promotes colonization by submerged and emergent aquatic plants, macroinvertebrates, and fish species. This project is expected to improve recreational fishing opportunities due to increased and healthier fish populations.
