Ever since I started fishing for carp last September on my Waupaca lake, I have been catching them consistently, 2-4 every weekend, averaging 8 lbs, through Fall and the same in the Spring and Summer.

Then in the middle of August, it just shut down. I've done nothing differently, but I've caught 2 carp in the last 3 weeks. I've noticed a big difference in activity in the lake as well. Mornings and evening, multiple big carp splashes were common. Now, the lake is like the dead sea. It's like the carp just all went dormant. 

Can anyone explain what happened?
