Thinking out loud and wondering about the May Fly hatch.
Each season the hatch occurs about now and some years they are more numerous and other years, not as many. I live in western Toledo and at times we'd get them "big time" and other years not at all. Any thoughts as to why things happen like this? Is it simply the wind directions that blow them this way? Could it be that there are more fish here in the western basin during certain years and thus getting their fill that helps to keep the fly populations down?
Any thoughts?
