During the spring and early summer the DNR uses an electric trap to control the Lamprey in the river. The lampery attaches itself to a fish much like a leech would and will eventually kill its host. The traps are taken out around the first or second week in July. Until then you must portage your canoe over a short trail, shown left, and back into the river. The nice loading docks make this a very easy task. The trap shown left is not electric but a long funnel leads them into a trap. You may pass a few of these on this part of the river.
