 Anglers target this species in a variety of waterways, including small rivers (barely large enough for a canoe), large rivers (such as the Missouri, Mississippi, Ohio, Tennessee and Colorado Rivers), and reservoirs.A common element of flathead catfish location is submerged wood cover such as logs and rootwads which often collect at bends in rivers.A good flathead spot usually also includes relatively deep water compared to the rest of a particular section of river, a moderate amount of current, and access to plentiful baitfish such as river herring, shad, carp, drum, panfish, or suckers.
