I'm heading to Canada to fish on a channel of Lake Huron. The last time I was there 2yrs. ago around the 4th of July, I remember the locals talking about the fishing being slow because of the may fly hatch. We are planning on heading up June 1 and staying a couple days. Does anybody know exactly when the may fly hatch occurs up there? I understand their called a "May" fly but I know they hatch at different times depending on the location. I appreciate any help!!
