In case you are wondering Clem, that's Murkey Creek on highway 584 as you head toward Nakina. There is a boat launch at the bridge, and that rapid is about a kilometre downstream. There is a very short portage river left right before the rapid, or you can shoot it if you hang tight on the left. Why should you know this? Because the fishing right below the rapid is phenomenal in the spring. You can proceed from there down through Arm Lake, Poilu Lake and eventually into Burrows Lake. All good fishing!
