In Kansas, it appears to be already largely extirpated from the Cottonwood River and some of its tributaries, and from Shoal and Center Creeks; but persists in large stretches of the Verdigris, Neosho and North Fork Spring Rivers. It was also previously reported locally extinct from the Fall River, although captive juveniles reared in restoration projects have now been successfully reintroduced to this river. Within Kansas, population densities are reportedly considerably higher in the Spring River than in other streams. This may be because of the Neosho mucket's apparent ability to securely anchor itself in the suitably loose substratum of the Spring River along with the markedly fast water currents in this river.
