Two-Story Lakes are those where coldwater fish, such as salmon and trout, move to deep, cold waters during the hot summer months while warm-water fish, such as black bass and bluegill, remain in warm surface waters. Discussed in detail is the equipment needed to withstand the stress created by trolled lines and large fish, including the lines and backings required to reach certain depths and the knots necessary to prevent leader breakage. Specific fly patterns are featured, as well as the hooks to tie them on. Included is a presentation of casting; trolling; wind drifting; pier, breakwater, and surf fishing; back-trolling and back-bouncing; and techniques to fight big fish.
