Plenty of water to launch & retreive your Glastron. And there's plenty of water in the lake for the kind of draft clearance you have. Just be on the correct sides of the markers.

I navigate by the phrase "stay South or West of Red". Black is opposite. But the chart clears up any conflicts or where the transition occurs.
Fall is the best time, there is smooth water, fewer boaters, and the water is warmer than in the spring. All you want is low winds to keep down the chop. If it gets too windy you can run nearer the shore it's coming from to hide from the rough stuff.
