yes, starting in mid-August you can experience bloom and it can get pretty nasty at times. i’ve run through giant “oil slicks” of it with the boat where you can feel the boat slide and behave differently and smell the chlorophyll as you disturb it. i won’t cast where it’s thick enough that i can’t see my lure or my line drips green. that said, it’s my favorite time to fish up there as the cool nights create some great shallow rock bite opportunities.
so, the answer for us is simply to drive. admittedly, this is easier when you know the lake well, and it can require being willing to burn gas to run 15 miles to the right section of the lake. LotW is huge and has lots of current, so the bloom isn’t piled up like that everywhere. the wind and current will push it up against shorelines or into neckdowns, but on the other side of that neckdown will be usually be clean water. were you staying at Tamarack? that’s a good location to usually be able to reach cleaner water. for example, if the wind is southerly you can find clean water on the south side of Miles Bay, or over in Little Traverse near Alexandria/Huggins. if it’s westerly you can typically find clean water northwest of Boomstick Island. if you’re up for fishing reefs in the open basins there will be less bloom on the downwind end of the basin and more on the upwind end. (when we were up in August this year there was 3′ visibility on the south end of a basin we like, and 6″ visibility on the north end of that same basin.) the hardest can be when it’s calm and the wind isn’t moving the bloom, in that case look for natural current areas where the bloom socks in on one side of a narrows and is cleared away from the other side.
