The Wisconsin DNR and the Menominee Indian Tribe of Wisconsin (MITW) have been jointly working on a project to restore lake sturgeon to the upper Wolf River within the Menominee Tribal Reservation. Efforts date back to the early 1990s and capture and upstream transfer of subadult and adult lake sturgeon has been the primary method for restoring access of sturgeon to their ancestral spawning grounds below Keshena Falls.
