Nonindigenous Occurrences: The Tadpole Madtom is known from the Snake and Boise rivers in Idaho (Linder 1963;Taylor 1969; Simpson and Wallace 1978; Wydoski and Whitney 1979; Idaho Fish and Game 1990); the upper Chicopee and Thames rivers in Massachusetts (Hartel 1992; Cardoza et al. 1993; Hartel et al. 1996); Frenchman's Creek, Hitchcock County in Nebraska (Jones 1963);the Merrimack River drainage in New Hampshire (Taylor 1969; Scarola 1973); the Muskingum drainage in Ohio (Hocutt et al. 1986); the Snake River drainage in Oregon (Taylor 1969; Bond 1973, 1994; Wydoski and Whitney 1979); the Rio Grande River in Texas (Hubbs et al. 1991); and the Columbia River in Washington, near the mouth of the Walla Walla River (Wydoski and Whitney 1979).

Means of Introduction: Unintentional in most locations. It is believed that introduced channel catfish and bullhead stock was contaminated with Tadpole Madtoms (Linder 1963; Taylor 1969; Simpson and Wallace 1978; Wydoski and Whitney 1979; Hartel 1992).

Status: Established in Connecticut, Idaho, Massachusetts, New Hampshire, Ohio, Oregon, and Washington; reported in Nebraska and Texas.

Impact of Introduction: Unknown.

Remarks: Introduced populations in Washington resulted from the downriver dispersal of fish introduced into Idaho rivers (Wydoski and Whitney 1979). The Tadpole Madtom has not been collected from the Thames drainage in Connecticut (B. Gerrish, personal communication). Record from a lake near Poteau, Oklahoma, may be the result of an introduction (Taylor 1969).
