This is gonna sound crazy but yesterday was fishing the Au Sable between Rea Rd. and Whirlpool for smallies and I noticed a very large dark fish swim past in front of us. I could not make out for sure what it was but I swear it looked just like a big king! I thought I was just mistaken and it was probably just a big dark carp. Fished another 15 minutes or so and I was amazed to see what was apparently the same fish swim up onto some shallow gravel and start splashing around like it was trying to spawn! Looked like a 12 to 15 lb. king that was very dark and green! Had the whole back out of the water so I got a pretty good look at it this time. Tips of the fins had started to turn white on the tips too. Never heard of this before, anyone else seen a king up in here this time of year? Crazy.
