Not that I know of. I have always referred to it as the West Newton landing. I thought it was supposed to be temporary during the draw down, but it has been around for a few years now.
Half Moon is the original ramp that has been there as long as I can remember. Half Moon was closed recently due to high water, but it may be open now. I have not been down that way yet this spring so I can’t give you an update. I usually drive to the WI side and launch in Alma during the early spring.
