Also here is a view of what I call the sunken island and it is under water until the lake gets down about 5' or so then shows above.
After the fact I thought about this thread which explains it better and has some questions that I answered too.
3D Image explained better...
One I marked up to show the area better...
The red arrow is near the sunken island and the yellow line goes around it and also shows where the tree line is. The green line is the boat lane.
