We have had our boat in for two weeks and havent made a run due to muddy and rough water. i have never fished the detroit river but i the town i live we get a walleye run and this year has been super hot. i have heard stories of guys taking 25 walleye out in like 2 or 3 week ends. as far as the lake goes i think next weekend (18-20)will be great they are callin for good weather all week
