Mike, you are so right about your statement. Most forum members weren't around when I fished the Little Lehigh starting in the early to mid sixties. The stream was so different then. And it had a heckuva caddis hatch in May. I always heard they were a hardy species, but they are gone (unless someone else can me they do exist today). There used to be a large spring aside of the stream where a few trout took up residence and I remember dappling flies, trying to catch them. That is long gone.
My mentor was much older than me, and he told me there were grass beds and green drakes before my time. The Little Lehigh will someday become nothing more than a drainage ditch. How sad.
