Can be a tough lake to crack 10 point... but they're there, no doubt about that. Smallies seem to hit most anything.. even 10" Muskie baits. Find a shoreline rock pile.. any rock pile and cast a crank bait at it and you'll find a bass.
Walleye... best bet for success... pick any channel marker and fish between it and the rock pile it marks in the last hour of day light. 3 inch live minnows or a yellow grub twister tail jig. The 'eye's are use to eating grubs off logs etc.. They also seem to like perch pattern crankbaits about 3 or 4 inches long. I've caught my best from my dock on same.... as well as pike to 35" so far.
Whitefish... I'd suspect you're jigging bottom just like in the winter. Find a mud/silt flat and try some small jigs, micro tubes, rubber crayfish etc a few feet off bottom. If they're hungry.. they'll come up and nail it.
Lakers by late June, depending on water temps will just be starting to go for the depths. Some years we're still flat lining spoons that only run about 8 feet down.. and others dipsy diver or rigger down about 25 feet and we pick a fair number of eaters up.
If you are staying at Tamar... there's a deep oval hole off the West side of the island there. Depending on water temp.. find the structure changes vs correct depth for 52F water and troll it, or jig it. You'll find them..
