Beneficial Use of Sediment 2025
Excess sediment and century-old sawmill waste dredged from the St. Louis River estuary was used to create islands, fish habitat, and fertile bay bottoms for the restoration of 230 acres of coastal wetland.

Use of dredged material helps stretch restoration funds

The Grassy Point and Kingsbury Bay aquatic habitat restoration project is notable for the many moving pieces behind a creative design at two locations in an estuary adjacent to Lake Superior. Submerged, century-old sawmill waste was dredged and used to create a protective island. Excess, organic-rich sediment was transported from one site to provide a fertile environment at the other site. This innovative use of on-site material was critical to making the most of our client’s restoration budget.
