Where can I get a topographic map for the local reservoir I fish? I have looked everywhere.

What lake, state, name?

that may help us lead you in the right direction.

Try angling-technologies to see if they have your lake mapped. If not, send them an email, and if the data is out there, they'll add it.

Thanks I'll try it out.

Navionics has a new PC maps edition, Navplanner 2, which has topo maps for most lakes. You can check and see if your lake is on it before you buy.

I found a lot of underwater structure using a combination of their PC map and my Humminbird side view. Most stuff is right where it's marked on the PC topo map.
