North twin has historically been dominated by rough fish, including bigmouth buffalo and common carp. 140,000 pounds of buffalo were removed in the spring of 2019 and the water clarity had improved some. If the water clarity improvement is maintained anglers can expect to see better bluegill, crappie, and bass fishing in the coming years. North Twin has a decent walleye population. The densities are not as high relative to other natural lakes in the region, but the fish are large and many of the fish range from 22 to 27 inches. The channel catfish population is strong and there are many fish from 2 to 5 pounds in the lake. Hybrid striped bass, northern pike, and largemouth bass were stocked following the buffalo removal, but it will take several years for these fish to recruit to the creel. Walleye and catfish are stocked on a regular basis. The yellow bass numbers have declined substantially, but their size has improved slightly. - Last updated on 08/01/2019.
In nearly all cases, Iowa fish are safe to eat. Cleaning and/or preparing the meal causes most of the problems regarding taste or color of fish. Like all living creatures, fish are susceptible to diseases, parasites, and other naturally occurring conditions in the water. If you suspect your fish is affected by any of these conditions, do not eat it. Consider eating smaller and younger fish which usually have lower levels of contaminants than larger ones. Most contaminants accumulate in larger, older fish. For additional information, check out our resources for eating and cooking Iowa caught fish.
