While DougC and I were out on Sunday (second time ever on the river in my boat (the one with the brand-new 115hp Yamaha)), we were slowly exploring the area right below a wing dyke and I was caught off guard when the depth suddenly went from 8 ft to to about a foot or so and I was dragging my lower unit in the mud. I couldn't tell anything visually about the water that would make me think it was shallow, which contributed to my surprise. Fortunately, we didn't have any trouble getting off the mud, but it kind of spooked me for the rest of the day and we avoided a few places that we might have been able to get into, for fear that we'd get stuck in the mud. My boat is heavy enough that I suspect it'd stay put once run aground, and I still recall my experience (in my other boat) with shallow water on Truman Lake last fall that I'd rather not repeat. So what are the words of wisdom from those of you who've fished the river more than me? Am I worrying about nothing, or is the likelihood of getting beached on a mud flat high enough to warrant extra caution? My real worry is getting on the upstream side of a shallow spot and being pushed farther onto it by the current, unable to do anything about the situation. And supposing that I find myself stuck one day, what's the best way for getting unstuck?
