My favourite smallie lake turned over in the last couple of days. I was out Sunday and it was 65F and clear, clear, clear. I could spot boulders in 18' of water, and see depth changes just from the colour change of the water. They were hugging bottom, but still hitting.
I got out for a bit yesterday: 62F and about 4' of visibility. The fish either moved or had shutdown. I couldn't buy a bite, even on the regular hotspots. Looking forward to the post-turnover bite.....that's when the big ones start hitting.
