Fishing Dexter Marsh in Musky, Tiger Musky & Pike (ESOX) Posted June 16, 2015 it's shallow. waters come up a bit in the past week. I have a cabin there and it's tricky getting the boat in to my dock. you'll be ok with the trolling motor I'd think. I've been all around the grass islands and it's 2-3 tops. there's 2 or 3 channels in there but by channels I'm talking 5 feet. The main channel drops to 9 feet in a few places that's where I've caught the most fish. It's tricky getting in there. There's a large sandbar that runs parallel to the black river. there's a small point right near the first bouy heading up river. you can sneak in there but you need to be within 30' of that point to not get stuck on the bar. Made that mistake my fist time out. Otherwise you outta be ok. Don't bother getting too far towards the military rd launch, it's super shallow and there's some pipes sticking up just below the surface, you can't see them now but they're there. See lots of pike and bass jumping in the evenings when I'm sitting on my porch. There's no signs but it's understood that area is all no wake, lots of boats and docks in there so just go easy once you get past that point. If you head in PM me for more info. Neighbor kids caught a bunch of bullhead off my dock saturday night, so that's an option as well.
