Lake Onalaska Project for Fish Habitat and Improved Boat Navigation
The Brice Prairie Conservation Association is sponsoring a project on the north shore of Lake Onalaska to improve fish habitat and boat navigation via dredging. The last significant dredge project was completed in 1989. The necessary permits for the project have been approved and if we achieve funding goals a Fall 2024 start date is planned. Past projects involved public and private funding.
