Book excerpt: This little lake Bible organizes and explains lake types, how to read and fly fish them, and understand and imitate their aquatic insect life cycles -- and nearby terrestrial insects. Next to each color insect photograph is a representative fly pattern. By carefully inspecting the lake for insects you can find the correct fly to use as shown in the book. Hatch Guide for Lakes is the golden key to unravelling one of fly fishing's last best-kept secrets.
