Early in the spring, when snow water is running into the stream, fly fishing is almost useless — with some notable exceptions. May, June and July are the
prime trout months in most waters south of Canada. In late summer small streams get very low and clear, requiring extra precaution on the part of the angler to keep himself and his equipment as much in the background as possible. Fine leaders and small flies are the rule for this clear water fishing. The anglers should cast toward the sun to avoid making shadows; he should drop his flies as gently as possible and fish the shady side of the stream. The expert under these conditions is quick to take advantage of every opportunity such as casting under the shade of overhanging trees, fishing when a cloud momentarily hides the sun or when a breeze ruffles the surface of the stream.
