Can anyone share some info on what things are like during July, Aug, Sept? Looking for info on bugs, crowds, fishing, etc.

June bugs and good fishing
July berries and bugs, watch for storms
August crowds, fewer bugs, great swimming
September, mixed crowds bugs going away, mixed weather

July bugs are flies and mosquitoes. Gnats are done by then. Usually no snow. But cold rains still happening. Fishing slows down and it gets hot.
Early August brings lots of people. Bugs are around but kind of whatever-part of the deal as opposed to trying to carry you away. Fishing is slow in the heat and swimming is incredible.
Late August is great. Crowds drop off, water is still warm for swimming and you can already see shorter days and summer showing signs of packing up and heading south.
September is great. But surprisingly can be more people than you'd think. Usually no bad storms. Later in the month you'll probably see some snow. Bugs are gone. Bring wool, long leggings / sleeves and a beanie every month but especially June and September.

June you risk being ambushed by black flies but best fishing imo

July is too hot, too many bugs, but fruit.

End of august is amazing and hardly any bugs. Still people around though.

September is amazing. Less people, no bugs, decent fishing.

October is amazing. No bugs, no people, decent fishing.

Thanks everyone. Anyone know when the fall colors start showing up?

Late September

Late Sept, early Oct for color. As you move up through Sept. the weather becomes increasingly variable and the days shorter. Bugs are pretty much gone by 2nd week of Sept. People are fewer, especially deeper in the BW and mid-week.

+1 - The coldest day/night I have spent in the BW was the second week of Aug.

I'm assuming by gnats you mean black flies. I have never been bothered by gnats as they do not bite. Black flies on the other hand...They are the same size but very different in behavior.

In September the days will be getting noticeably shorter, making campfires that much more enjoyable. Also around the mid to end of the month the moose will be going into rut, so maybe you'll have an improved chance to see one of those crazy bulls.

By "gnat", I was referring to insects in the order Dipterans, family Simuliidae. This includes the black fly, called buffalo gnat in other parts. This insect is not the same as the no-see-um, which is even smaller, and is a gnat and does bite. The black fly, as called in the BWCA, is also not the same as the stable fly - the ones that bite the ankles (painfully) - Stomoxys calitrans, and also in a different taxonomic family. There are around 30 species of Simuliidae in this area of the country; some bite and some do not. Below is a link to a handy reference from Jaywalker, as it causes confusion, like my previous post.

I should have more clearly communicated that the approach to not letting insects ruin a trip is multi-faceted: one part chemicals if you will, one part physical barrier, and one part mental. Part of the approach is understanding a bit about the specific biting insect biology and ecology (if, when and how it bites). To say one technique / chemical / method flat-out doesn't work or works better than others on all biting insects is a bit unfair. I was trying to offer an idea about what insects might be more prevalent than others, so the original poster could perhaps get an idea about control. For the insects in Simuliidae, I find DEET not as helpful and physical barriers the most helpful. It's like fishing, only reverse.

Only thing I have to add is that September seems to be prime season for yellow jackets.

Which sucks, since I love September and I'm allergic to wasps :-(
