Are you planning to fish from a boat or from shore? There is limited areas to access from shore so I would highly suggest a boat. I have had great sucess with catfish and quite a bit of sucess with crappies. Walleyes are hard to find but there are some big ones in there. There once was a Professional Walleye stop at Coralville and I think in the two day tournament, less than 10 walleyes were weighed in.
Here is a video I made last year.

You can see that trolling in the res is a great way to have a lot of fun and catch a lot of cat fish…maybe even a ‘bonus’ fish at the end of the day.
I have been known to take complete strangers out and teach then the art of trolling, so if you have the desire to learn about trolling for cats, feel free to contact me and we’ll catch some cats together.
