Walleye anglers will continue to enjoy the “good times “as numbers of angler acceptable size fish will be harvested during the upcoming 2019 season. Catfish anglers will continue to enjoy quality angling as numbers of angler acceptable size and larger fish will comprise the majority of the catch for the upcoming 2019 season. Anglers will continue to notice the influx of panfish species comprised of yellow perch, crappie and bluegill in the 2019 anglers catch. Crappie anglers fishing the shoreline habitat and the canals during the early season will require sorting as anglers will note small fish in the catch; however, persistence will be rewarded with numbers of angler acceptable size fish in the creel. Continued good growth of the small black crappie population in Lost Island Lake will provide good angling opportunities for the fall and upcoming 2020 fishing season. Bluegill anglers, with persistence and patience will be rewarded with numbers of this species in the creel. Anglers will continue to catch the occasional yellow perch; however, anglers will be pleased by the size caught. Temperate bass, comprised primarily of yellow bass will provide plenty of “pole bending” action during the upcoming fishing season. Anglers will note the increased size of the fish population which will provide an upswing during the 2019 fishing season and beyond. Recent surveys reflect good numbers of northern pike in the lake which will provide excellent action during the 2019 season. Black bullheads will provide quality angling with numbers of large fish available for harvest. (2019)
