There is a dirt ramp on the west side of the lake off of Hontoon Rd, Tropical Marina on the north side has a ramp but it's very shallow ramp (had to put my truck in the water to get my Jon boat off the trailer) I usually launch at the bridge sr 44.
there is also a dirt ramp at the end of French Ave in Orange City. I may give it a shot in the morning myself.

Any tips or advise will need to come from someone else, I am struggling to catch fish this year for some reason.
