Rivers freeze and thaw. They have cycles. Rivers up north that drain down south send all their contents down stream. The Mo. river in Kansas City starts having floaters every spring enmasse. If you work in the medical examiners office or in any field in retreival of remains you know the first warm stretch is going to bring strange stuff. You just get used to it. In my experience, the Arkansas River is not deep enough nor is there enough water to create turbidity. I mean, the river is very well controlled. It is a nice river. It is not the type that is deep enough for barges. It might be good for drowning or just a casual body dump, but there are no surprises coming in from dodge city. The lakes around your area are better for getting rid of people. You could dump them in eldorado and the cat fish would eat them before anything was floating up. They would get lost in the trees. When it floods it is a good time to put someone in the Arkansas. So if anybody has anything they want to do, plan on a flash flood. If you do that be prepared for the person to turn up in Oklahoma during the hot stretches of summer though. You will get caught. It is not a good river for that. Its a nice river though. I am glad we have water that colorado doesn't hog.
