The fishery in Malvern Pond was last sampled in June of 2025. Largemouth bass sampled were up to 15 inches, Bluegill were small, averaging 4.25-inches and channel catfish ranged in size from 15 to 21 inches. The fishery struggles due the the presence of common carp. The lake was about four feet low at the time of sampling and the water was turbid (28") due to carp. - Last updated on 02/23/2026.

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.
