Samson, water temps are still fairly warm. We haven't had many cold nights lately, therefore the water temps have actually been rising on most bodies of water back into the mid to upper 70's. We do have some colder nights and average high temps coming in the extended forecast based on this morning. However some days next week look to be pushing back toward upper 70's and even 80.
That being said, typical late summer patterns should still be present. Last time I was out on Twin, we were marking a ton of fish around the 20 foot mark, while panfish were up shallower than that. There is a good deep weedline out there this year if you are looking for walleye. The typical humps and bars also are good spots to check at various times of the day.
Bass fishing has also been pretty hot on Twin from what I am hearing.
Musky fishing, if that is your thing is also going well out there. The recent Musky National Championship tournament out of Eagle River was two weekends ago. The longest fish came out of Twin, and the person that caught the most fish for the weekend also happened to be out on Twin.
Good luck fishing.
