283 --- I don't know about a map, but give this a try for fun.... go to
http://earth.google.com/ ...... in the right top if you want, click on Google Map free download and then click on the mac or Windows version and download it....
takes about 10 minutes if not on a dail-up internet connection.... this is the free version and I'm sure the Google Map Pro has better detail but never tried (one of those things that you get what you pay for things).... once downloaded, copy the "blue" google earth to your desktop or just click on the application from your files in your hard drive....
once it opens up, type in your address and it'll give you a satellite image over your house and just use the + or - to zoom in or out and the arrows to move around... the center piece actually lets you quickly steer your picture where you want to view ...
next just steer it down Hwy 111 where White County and Van Buren County meets and that should be the Caney Fork River..... go east and image is pretty clear and go west and it's clear just a little past Cotton's Marina, then the image is not quite as clear but you still get a pretty good aerial photo and if you zoom out to see a bigger picture, go all the way up to Rock Island and follow it up to Center Hill...pretty cool...it even shows little blue + signs that if you click on it, it shows a Natural landmark like Burgess falls, Great Falls, etc.....
Know it will be hard to take your laptop or computer in the boat, but maybe you can print a good image or have an idea where you're going without an actual map...... Nothing beats a map, but "real men" don't need directions either do we :-) tight lines.......
