Crowley Lake is under special fishing regulations as of August 1st. No live or scented baits may be used, and you may only keep two trout that are a minimum of 18 inches. You can still keep up to 25 perch but can not use baits to fish for them.
For perch fishing, use Sierra Slammer swim baits, or good old fashioned feather jigs. Get outside the week line between Hilton Bay and McGee Bay, or try on the Notrth Arm Between Leighton Springs and Alligator Point.
For trout fishing, the top lures are Thomas Buoyants, triple teasers, or rooster tails, fished in 8-12 ft near the inlets. Fish lures in Perch Patterns are also successful these days with lots of minnows cruising around.
