I’ve been to Camp Dodge several times and I always take a few fishing poles along. Below Sailorville Res. there are some very large cats. Last time I was there I remember one over 55lbs being caught. Go below the spillway, catch a few sunfish along the rocks and chunk them out in the deep holes. That’s how I saw a few guys catch some good ones, but you might want to explore further downstream to get away from some of the pressure as it’s real heavy below the spillway.
That’s just what I gleaned from the few times I’ve fished there and I’m sure there are more places to hook a big cat. ….Which reminds me we did catch some good ones on the northwest end of the reservoir from shore so you could explore the impoundment itself and connect with some good ones I’m sure.
