Smallmouth bass occur naturally in many eastern Oklahoma Ozark and Ouachita streams and tributaries. Fishable lake populations exist in Grand, Tenkiller, Murray, Eufaula, Texoma and Broken Bow.
Black bass is a general term referring to largemouth, spotted and smallmouth bass and their hybrids. The three species are similar, but can be easily identified. Since water clarity can affect the color of a fish , color is not a reliable way to tell the basses apart. The most objective way to tell these species apart is by the relationship of the eye and the mouth hinge. On a spotted bass, the mouth hinge lines up vertically with the back edge of the eye; on a smallmouth bass, the mouth hinge vertically lines up in front of the back edge of the eye; and on a largemouth bass, the mouth hinge vertically lines up behind the back edge of the eye.
Smallmouth inhabit clear, gravel-bottom-streams in Oklahoma. The best areas to fish for smallmouth within streams are in riffles, pools and the shallows above rapids. In manmade impoundments smallmouth seek clear, clean water usually with a rocky substrate. Weedy areas along the shoreline, flats off channels and shelves are all good areas to find smallmouth.

Spawning takes place in the spring when water temperatures reach 60 to 75 degrees F. Nests are built on gravel bars in three to 20 feet of water. The male drives a ripe female to the nest. After she lays her eggs, he searches out another, and then frequently a third female. Each female lays from 2,000 to 7,000 eggs per pound of body weight. Little or no parental care is provided after hatching.
During the day, smallmouth seek the refuge of underwater cover. In the morning and evening they are often found prowling the shoreline of a "home" pool. Many people consider smallmouth one of Oklahoma's feistiest freshwater sport fish. Once you catch one on light tackle, you will be anxious for your next encounter.
