Keg Creek Lake is a borrow lake along I-29 in Mills County. Like all the borrow lake in this area the quality of the fish populations are affected by fluctuating water levels and rough fish populations. Keg Creek was last surveyed for fish in 2012 and the results showed black crappie aboundant in the 6.5-inch range. Continued growth of these crappies is needed for them to reach a harvestable size. Bluegills were all equal or less than 7-inches. Common carp ranged from 16 to 22-inches. Largemouth bass were also sampled and ranged from 4 to 14 inches. Channel catfish were sampled in 2017 showing a large year class in the 11 to 13 inch range with fish up to 28 inches. (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.
