Both channel cats and flathead catfish are present. It is not uncommon to hear about a 50 pound plus flathead caught under the Oregon Dam. Most of the bigger flatheads are caught using bluegills. The law on the use of bluegills as bait is they may be used as bait as long as they are not transported between waters. This means that you can use them as long as you caught them in the same body off water you are fishing in.
Channel catfish are extremely abundant.
The best time to fish for them is after the water heats up in the summer. Fishermen use all kinds of stink bait and chicken livers to catch these fish. Anything that smells bad such as rotten shrimp is another good bait. Look for these cats under dams, in the deeper holes or around log jams. The stretch of river between the Oregon Dam and the Grand Detour Bridge is an often-overlooked hotspot for a variety of species of fish.
