Can anyone point me in the right direction of a Contour Map of Presque Isle Bay and the surrounding lake?

try fisherie.com   they have some really good maps of elk and walnut creek up there    idk  but its worth a try

Yeah I've seen the maps on fisherie.  I'm looking for the depth contour map of the bay and the lake just outside of the bay.  

I think I saw it on an earlier post, but I couldn't find it again.

Here ya go.......

Also FCB:

Since it says you are from Pittsburgh, I forgot to tell you that I bought my Lake Erie map from Lock 3 tackle shop a few years back, which is right across from the Harmarville Dam, on Freeport Road. The map I got gives all the details you were talking about for that area.
