At some point they raised and later, in the late 70's I think, lowered the lake level. The sand has been collecting there for 40+ years forming the new isthmus. The Alder thicket follows in a few years and holds it all in place. Kinda cool to see such a dramatic change in a few decades actually. My first trip out of French began paddling past mud banks and drowned, ready to fall trees. It looked creepy. Really creepy. In a word, ugly. These days there's new beauty around every corner - and there's a lot of corners in that short little stretch.
