Topo Graphs for NJ Lakes?

[JVO]

Hey guys, been reading a lot about topo charts recently and I've been trying to find some detail ones for the lakes and reservoirs up in northern jersey (monksville, echo lake, and the other Newark watershed lakes).

I reviewed the NJ Wildlife website, http://www.njfishandwildlife.com/lakemaps.htm, but their maps aren't very detailed.

I also downloaded the Navionics app on my iphone, but it also wasn't as detailed as I was hoping. Was wondering if anyone knows where I could get a hold of a decent map or if their is a website with a database that has some.
