I have the National Geographic seamless USGS topographic maps for Arizona on cd-rom. Send me a PM and let's see if these disks would help to create a custom map for you.
If that doesn't work look online and you can find a lot of cd-rom disks with anything you want from topo's with water to just about anything else. I've got one and it has helped me to find quite a few water spots that are a long ways from the road.
