You could go to Navionics.com, then click on chart viewer, then zoom on Conneaut lake. Then when you get to the desired zoom level, hit your print screen button and paste it into paint and print away. Do it multiple times for the desired areas.
Is it a pain in the butt? Yes, it is.
Do you get your contour map of Conneaut in a round about way for the cost of a few sheets of paper? Also yes. :)
If you have a friend with a laminator, the maps will last for quite awhile.
Or you could purchase a subscription to Navionics Boat app and get it that way for iOs or Android. But that costs money.
Just trying to help.
