I went up saturday afternoon, it seems alot lower then -2.5. There were many rocks showing above mcCoys that I hadn’t really seen all sumer. Then again that could have been affect by that dam on the quebec side
it kinda turns into a funky little wave hole at -2 3/4 havent really run it much lower than that but i think you don’t have much to worry about in the way of rocks. the one that makes the wave is pretty far (surfers wise) away upstream. horse shoe is a different story all together… it gets kinda bony in some spots but the surf on the very middle part of of the wave (favoring left side) isn’t bad but in the foam pile is where the rock is that makes baby face is.
