The final report of an unusual, three-year study shows that new gates of the dam are blocking some fish heading upstream.
So why care what happens to a bunch of fish many people have never heard of before - white suckers, smallmouth bass and shorthead redhorse?
The provincial work permit that allowed London to rebuild the dam required the city to monitor migration to make sure fish can move through the new open gates of the dam as easily as they did before construction.
