same here, been driving on for 3 weeks, on saturday there were about 50 trucks out there.
Funny enough we drove past the large group of people sitting about 200m off shore and we continued out about another 100m. We pulled up about 150 perch, kept 39. the group nearest us but still close to shore only caught 2. This is the second time I've had this happen
so my advice is find the deep water, load any hook up with maggots and put it 3" off the bottom. I tried everything from forage minnows to 5 of diamonds to wire worms, swedish pimples, even went up in size to a buck shot rattler.
My plan with the buck shot was that would bring in the bigger perch, and it did, a few about 11", but I ended up just snagging a whole lot of little ones by setting the hook when i felt something and just catching them outside the mouth, so they all went back. I also brought up a tiny pike on that buck shot, but id recommend not using it becuase it just allowed the perch to pick the hook clean and I was constantly re baiting.
My little pike, dog is totally not impressed
