Fished the Detroit River Friday afternoon and Saturday morning trolling bottom bouncers and crawler harnesses down stream. Ended up with 10 fish both Friday and Saturday. Bouncers were 3oz and harnesses were Walleye Kid Custom Harnesses with 36” lead, gold blade (#5), and perch beads. Speed was 1.9-2.4 MPH on GPS. We fished around a pack of jiggers and caught fish consistently while they hit only a few fish. Most of the fish came from Great Lakes Steel from the north end of the mill to the flagpole. Best area was in front of the pile of big rocks on shore near the north corner of their property in 35-38 FOW.
My buddy & I fish GLS on Saturday (7:00 until 12:30) & I had my limit at 8:30 (jigging). Most of our fish came between the rocks & flag pole in 35 to 40 fow. I seen a few guys pulling harnesses down stream, maybe you were one of them. We were in a blue/gray Princecraft.
