Neosho Bass
Micropterus velox
A stream bass of the Ozark highlands, long treated as a subspecies of smallmouth bass and now recognised as its own species. It lives in the clear, rocky streams of the Neosho and Arkansas river basins in Missouri, Arkansas, Oklahoma and Kansas. Identification versus smallmouth bass is genuinely subtle — where you caught it is the best clue, since outside its Ozark range a 'Neosho' is almost certainly a smallmouth.

Identifying features
- Bronze-green bass build nearly identical to a smallmouth — range is the best clue
- Found only in Ozark highland streams of the Neosho/Arkansas basin
- Faint vertical barring on the sides, plainer than a typical smallmouth's
- Jaw not extending past the eye, with small scales on the cheek
- Red to orange eye and reddish fins, especially in the breeding season
Habits
- Holds in rocky pools and current seams like a stream smallmouth
- Feeds heavily on crayfish, plus minnows and stream insects
- Spawns in late spring on gravel nests in quiet pool tails
- Most at home in clear, cool, flowing water — rarely in lakes
- Often shares streams with true smallmouth bass, and hybrids occur
Distribution
Where to find them
- The Neosho (Spring) River and its clear tributaries in the Ozarks
- Illinois River and Baron Fork in northeastern Oklahoma
- Rocky pools of Ozark streams in southwest Missouri and northwest Arkansas
Where they live
How to catch them
Small lures and flies in Ozark streams Shore
Rig: Light spinning or fly tackle waded in clear streams, casting small jigs, spinners or streamers to pools and current seams — it behaves like a stream smallmouth
Bait/lure: Small soft plastics, streamers
Key tip: Wade quietly and cast tight to boulders and ledges; clear Ozark water makes these fish wary.
Crawfish imitations around boulders River
Rig: Texas-rigged or jig-head crawfish plastic hopped slowly along rocky bottoms and bluff ledges
Bait/lure: Crawfish soft plastics
Key tip: Crayfish are the main food — fish the craw slowly through the deepest part of each pool.

Baseline setup
- Rod: Light to medium-light 6-7 ft spinning or fly rod

Good — firm white flesh like smallmouth bass, though stream populations are modest and many anglers practise catch and release.
Similar species
Smallmouth BassSmallmouth bass is widespread across North America with usually stronger vertical barring; Neosho bass is confined to Ozark streams of the Neosho/Arkansas basin and looks almost identical — location is the practical separator
Spotted BassSpotted bass has rows of dark spots below the lateral line, a smaller mouth and a tooth patch on the tongue; Neosho bass lacks the spot rows and tongue patchRegulations vary by area and can change in-season — always check the official rules for your area before you fish.
