We're looking at planning a trip up the Mississippi and Ohio Rivers starting at the Arkansas River, time frame maybe late spring or early summer. We have driven over the Mighty Mississip several times but have never taken the boat out on it. The boat is an 80 footer with twin 305hp Merc I/O's and no thrusters. Does anyone know of any references where we can find info for preplanning, such as river flow rates and what would be a go/no-go current, fuel stops, safe anchorages/marinas, overall do's and don'ts, and anything else any of you can think of? The Mississippi can be a bit intimidating. Any and all advice is appreciated, and thanks in advance!
