This is our fist year on Lake Erie and the Mayflies are Nasty. It is hard to go and enjoy the boat when you and the boat are covered so heavily is Flies. 1) Typically is there a strong bloom and then it becomes less dense for the summer or does it stay strong through summer? 2) Are they better or worse in certain parts of the lake. We are wanting to head over to PIB and a few of the other islands over the 4th weekend, however we are hesitating due what it has been like the last 2 weeks.
