Commission OKs design for river fish sorting project

May 30, 2019

DETROIT (AP) — The Great Lakes Fishery Commission has selected the final design for a project intended to allow removal of dams from rivers without letting exotic species migrate upstream.

The ”FishPass ” initiative will take place on the Boardman River in Traverse City, Michigan, which is undergoing a restoration program that includes removal of several dams .

At the site of the last dam to be removed, a barrier will be installed to prevent parasitic sea lamprey from swimming upriver and attacking native fish. The mechanism also will include a channel where fish-sorting techniques and technologies will be tested.

The goal will be to block the path of unwanted fish while letting the others continue upstream. A second channel will allow recreation and normal water flow.

The commission approved the design Wednesday in Detroit.
