Sorry - not trying to get in on every conversation here - just trying to be helpful. If you don't want to pay for a subscription to our site we still let you see a lot of free information to include nationwide USGS maps that often show contours from before lakes were built. Click on Maps - free features - then click the box next to Topo Maps and the USGS topo maps will show up. You might have to zoom out a bit to see the detail you want.
