Targeting trout in deep water is best after a strong cold front. When water temperatures drop to the upper 60s, most trout find warmer water. Target deep holes (6-12 feet) close to flats, residential canals and mouths of rivers. Residential canals with a southern exposure have the warmest water. Fish the northern side of the canal, which has the least water movement. The turns of a river mouth have deep dropoffs and are good areas for trout to find food. Look for trout to move to the shallows closest to hole in the warmest part of the day. They will lay in a foot of water and spook if not approached quietly. Fish deep holes near the flats and residential canals with a sinking hard-body plug or a jig heavy enough to reach the bottom. The hard-body plug should have a white or gold side. Reel the plug slowly across the bottom and twitch the rod tip every few cranks of the reel. This makes the plug turn on its side and flash when the sun hits it. The same approach works around river mouths. Work the lures as slowly as possible to give trout time to strike.
