This 79-mile stretch starts at the Minnesota border extending through Decorah to the Lower Dam which is about 11 miles northeast of Decorah. The headwaters of the Upper Iowa starts in Minnesota near Leroy. The Upper Iowa is a paddlers' dream, but if you don't want to share your experience come during the week especially in the summer. There are three dams in this stretch that must be portaged around, the Lidtke Mill Dam near Lime Springs, Upper Dam about 6 miles and Lower Dam 11 miles both northeast of Decorah. There is so much to see from the Chimney Rocks to Malanaphy Springs as one paddles. It's also an outstanding fishery. The Upper Iowa boosts trophy sized Walleye thanks to the IA DNR's interior river Walleye stocking program, but also has an excellent Smallmouth Bass fishery. During April and May, be prepared for some amazing sucker fishing. - Last updated on 02/08/2022.
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.
