Fishing Forecast

Lake Manawa is a shallow 772 acre oxbow lake of the Missouri River. Water from Mosquito Creek is fed into the Manawa to suppliment water levels during the year. Sixteen different fish species have been documented in the lake. The fishing centers around 8 (black and white crappie, bluegill, largemouth bass, walleye, wipers, channel catfish, and flathead catfish). The walleye, wipers, and channel catfish originate from fish stocked by the DNR. Walleye and wipers provide an additional preditor in the lake as well as some exciting fishing. Crappies in the lake are cyclical and their populations vary from year to year depending on the size and number of the dominate year class. Last falls fishery survey showed good numbers of 10-inch white crappies and a few 11-inch fish remaining in the population. Very few bluegills reach acceptable size for anglers in Manawa. The largemouth bass population is low in numbers but contains some quality sized fish. Fair numbers of walleyes above 17-inches are present with fish up to 26-inches. Annual wiper stockings have produced multiple year classes in Manawa. Last falls survey showed good numbers of 18 to 19-inch fish and fish over 20-inches in the population. The channel catfish population is abundant and fish range from 15 to 28-inches.(2014)

Iowa-Caught Fish Are Safe to Eat, In Almost All Cases

The vast majority of Iowa’s streams, rivers and lakes offer safe and high-quality fish that pose little or no threat to human health if consumed. Some limitations may apply for young children and pregnant women. Here’s a Fish Consumption Fact Sheet from the Iowa DNR and the Iowa Dept. of Public Health for more information.
