I checked out the launch yesterday. It's not that bad I'm glad to still have access,but I will not be able to get my 14' boat in, that's ok with me I like talking the kayaks. I think a guy or 2 could still push a 12' aluminum boat and trailer past the rock barricade to the lake.but I don't have one to try sorry for that."the walk is not that far" IMO although the walk to the trailer parking lot is up hill which is about twice the distance. The lower lot has 3 spots no trailer,the upper lot has 4 maybe 5. Before you try launching a 12'. I think it's best for you to go look for your self, before trying.
Sorry I should have taken some photos, maybe next time.
Edit added a goggle photo
