Catfish are classified as warm water game fish, preferring water temperatures from the mid-70s to 80s. They're found naturally in large warm water rivers, including large tributaries of those waters, and have been stocked in many lakes and ponds. Catfish can tolerate muddy water but, contrary to popular belief, cannot survive where pollution levels are high or dissolved oxygen levels, low. Blue cats prefer clearer, faster water than the other catfish species.
Natural lakes have stable water levels; outflow balances inflow, and except in times of serious droughts, depth changes only a few feet between rainy and dry seasons. Many reservoirs, in contrast, alternately store and release water. Inflow and outflow are seldom balanced, and the surface level is often rising or falling.
