A little late but for what it's worth, the first week of August fishing report for the Whitefish chain is as follows, at least from our boat:
Knocked Northern silly in middle Whitefish in 35 to 60 ft. water around the humps on the southern half. Chartreuse, or dark green deep diving rapalas seemed to be the favorites choice. Used the solunar tables as a guide.
Caught lots of northern south of the two islands in Cross, 30ft water. double bladed spinners with rubber worms, and again, deep diving rapalas, but only dark green seemed to make them happy.
Didn't catch any walleye, but we were boating tons of northern, (kept just enough to eat) so we weren't bored.
Overall caught and released approx 10 northern in the 25 to 30 inch range over four days. Lost count on the little ones.
Struck out altogether on lower Whitefish.
Caught a four pound large mouth using a split shot rig and a large sucker about a half mile south of Moonlight Bay (west side) on Cross. Also caught a couple of northerns in the same spot jigging with red tails in 12 ft. of water, just off the weed line. Biggest caught there was a 5 pound northern.
Sorry for the delay on the report, but maybe this will help somebody a little...
