Thanks much for all the replies! First, trust me when I say that this group has a high level of respect for the river. The troop has been doing this trip for a number of years and the first guy to lead it realy instilled a high level of "leave no trace" philosophy. We also make a point to have the scouts clean up each camp and landing site to where it is better than when we arrived. I also don't tollerate any of conduct you might have seen from others although some boys seem to have a tendency to catch the occasional frog, snake, or lizzard. One accident or injury from something like that completely ruins the experience. I'm not a 'fun dad' or 'fun leader'. But at the end of the trip, fun will be had. We told the boys a trip to the hospital begins in a canoe. I really apprecaite the lure suggestions espcially pinching down barbs or going barbless. Hook accidents are no fun and it makes catch and release much more doable. I plan to discourage fishing from the canoe early on as the river requires a bit more attention early. Further down stream I think I can let them fish while on the water.
Last year was my first trip on this river. I've done numerous canoe trips over the years but mostly in Wisconsin and Canada Boundary Waters. I had an inaccurate image of Missouri Rivers as slow, warm, amnd muddy. I had no idea there streams like this in Missouri. You have a great resource!
