Where can a person buy good topo maps to use for fishing?  I've got several topo bought at large sporting good stores, such as fishing hop spots maps etc.  These maps give a good over view of the lakes and are good for navigation (sometimes), but topo details are pretty vauge or the scale is of no real use.  Can anyone point me in the right directions?  Thanks in advance.

Check out MyTopo.com.  You can preview the map before you order, it takes a few minutes though.

another good website you can try is www.terraserver-usa.com. they have some really good pics as long as you know the address or lake name. hope this  helps

I have been a terra server fan for year. Found one better....

Zoom in and then in the top right go to satellite view. **You will NOT get depth lines with these, only a satellite photo**

I haven't been able to find a good underwater topo map on line. Except for Mytopo.com. I have found the no mater where you live or fish. You can find a good fishing map by calling or visiting a tackle shop in that area. These maps are usualy hard to beat.
