Such an enthusiastic view of Coralville from someone who’s actually fished there? All kidding aside, I fish it alot more than I care to admit and it is spotty at best for walleyes. Usually you can get them in a very small spot when something specific is happening (like flood stage, high winds, or ice-out). Below the dam used to be very good, about 10 years ago. Now I spend a day every week or two down there from fall through spring and I do well about 1 in 10 trips. I do alot better for numbers and size in Pleasant Creek, Mac Bride, the Wapsi, and even the Cedar. But, Coralville is a catfish factory.
