There is a ramp, but then you are in a river that goes another 50 yds around a bend into lake MI. Last year the water at the mouth was only inches deep, so bypassing the ramp and using a cart right across the beach near the ramp allowed you to go directly to deeper water. Seems like someone said the river mouth was deeper water this year (since the lake is so high) so should be good to go.
Plus, if someone else is At the ramp launching with a cart, surely they’ll allow you to use it for 60 seconds.
