What to Fish For

Fishing Report

Ice Condition: Fishable
Water Temperature (°F): 33.0
Ramp Condition: Useable
Comments: River level is 14.9 feet at Lynxville and expected to lower slightly over the next week. Although predicted colder weather is building ice again, many shorelines and areas with current have weakened to unsafe levels. Stay on well travelled areas until safer ice returns. The boat ramp at Lynxville is starting to ice in again and may become unusable in the near future. Ice at the boat ramp in Sny Magill had eroded to unsafe levels last week, but is rebuilding. Anglers are crossing again. Use extreme caution; just downstream from the ramp is still open. Stay on well traveled paths across Johnson Sough. Last updated on 01/22/2026

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

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.
