Saginaw Dad,
I launched there last week. I don't really like to launch there because it's not really set up good. You either have to pull your boat up on the rocks (now that the lake is only a 1/2 ft low), or climb over the fishing dock. The only reason I launched there is because I got home late and only had an hour before dark, I literally live a 1/4 of a mile from this ramp so I went for it. I had no problems at all, the water was right at 4 ft all the way out to the main lake. I did have to dodge lots of tree limb piles, but it wasn't anything bad. You shouldn't have to worry about backing off the end of the ramp now that the lake is almost full.
However, unless you are in a time crunch, I would pay the $5 at West Bay.
