The clearest of them

Lake Willoughby is known for clear water. On a clear lake fish see a long way: lighter line, natural colours and longer casts make the difference.

Fishing deep water

Deep lakes reward slow, vertical fishing: drop a jig or a spoon to the depth where fish show on the sonar and work it right there. In spring and fall the fish come shallow and any method works.
