If you're looking for steady action on crappies, bluegills, yellow perch and some light-tackle walleye, give northeastern Colorado's Douglas Reservoir a look. Douglas, a state wildlife area, offers lots of public access and elbow room-it covers about 700 acres north of Fort Collins. During summer, Douglas's panfish congregate near structure in relatively deep, cool water. Most anglers use a boat and a fish finder to locate schools of bluegills, perch and crappies. Once the fish are found, vertical jigging with 1/8-ounce marabou jigs or Twister Tails draws strikes. Expect some crappies and perch to measure 10 to 13 inches long. Bluegills run a little smaller. For walleyes, anglers fish minnows with a bottom bouncer. Most of the walleyes are in the two- to three-pound range. The limit is 5 walleyes, 10 crappies, 20 bluegills and 20 yellow perch in aggregate. Contact: Colorado Div. of Wildlife (6060 Broadway, Denver, CO 80216; 303-291-7227).
