Paper Maps are getting harder and harder to find these days - but there is an incredible amount of technology you can tap into. Try Navionics South electronic "chips" (SD cards) for your electronic sonar/gps units or handhelds. They also offer phone aps for smart phones, all are under $15 and some are .99 ! They have recently made quite a few updates - especially for where you live in TX!

I don't want to come across as being a tit or pedantic but I think topographs are for land only (maybe different in the US though). There called Bathymetrical Survey maps here, the only place there available from here is the national library of Scotland. All of this is probably useless info to you as I'm not sure if the US has a equivalent of the national library but if they do I would try there.

ahh, yes, i think you are correct, topo is land maps. but bathymetrical survey is a little wordy, lol, but i think we all get the point now. i dont know about your state, but i know in wisconsin there is a somewhat hard to find database online of all past lake surveys. they are sometimes kinda out of date in some cases. but they can kinda help sort out some new bodies of water for you. here anyway larger more used lakes seem to be more acurate, some even support gps mapping, you might not be able to upload the whole map, but you can waypoint key fetures. might be worth looking into you states DNR/BLM/whatever they call it by you website and start doing some archive searching. good luck
