The smallmouth is a hard-fighting sport fish native only to a few waters in the southeastern corner of Kansas. Introduced in several larger reservoirs, the smallmouth has adapted well and attracts a growing number of angler fans. Smallmouths prefer clear water and rocky structure. The mouth of the smallmouth extends to just below the eye. The world record smallmouth weighed a whopping 11 pounds, 15 ounces. The Kansas record is 6 pounds, 6 ounces.
