Kinkaid Skunked My Friend And I

Well my buddy was fishing with a friend for about 7hrs today for muskie, they got skunked and didn't see a single fish. I trolled for walleye for about 4hrs and didn't connect with any fish either, I also threw some muskie lures for about 2hrs and didn't see anything. Water is about 42 degrees and the water is a little bit muddy. I did get to see a dog chase a deer with a broken leg out into the water, the deer swam all the way across the lake over by the spillway, I was surprised it didn't drown, it probably would have been better off just drowning. Anyone have any advice, I am going back out tomorrow, not really sure where to go, the only fish I was marking were out in like 40 to 60 feet of water suspended around 20-30 foot. I hate fishing deep!
