Jackson Lake State Park Professional Review and Guide
"Jackson Lake is a popular 2,800-surface-acre impoundment featuring a sandy bottom and shore in northeast Colorado. When the outlet ditch immediately below the dam is open (usually midsummer to fall), fishing for trout along the dam is generally good using Power Bait and salmon eggs. Otherwise fishing is best in the spring and fall.
For walleye and saugeye, the best action is in May and early June, along the dam or near any shoreline obstruction. Fish with minnows, Mister Twister grubs, or lead-head jigs tipped with a night crawler. Use a slow retrieve, the slower the better. Wipers run in the 15- to 22-inch range, with some larger caught every year. Without heavy gear, these fish will get away from you. Key Species: Walleye, saugeye, wiper, crappie, rainbow trout."
