Range
The species was once found throughout the Colorado basin, so occurred in Arizona, California, Colorado, Nevada, New Mexico,Utah, and Wyoming, as well as in Mexico. Damming and habitat alterations have confined the species to the upper Colorado drainage; currently, remnant populations are known from the Green River, Gunnison River, White River, San Juan River, and Yampa River. Additionally, land managers in the past have attempted to reduce the native fish population of the Colorado basin in favor of sport fishing. In the mid-1960s, the Federal government poured the poison rotonone into the Green and San Juan Rivers, attempting to create an environment supportive of non-native sportfish. They have been transplanted to the Salt River and Verde River, both outside their native range.

Famous quotes containing the word range:
“During the cattle drives, Texas cowboy music came into national significance. Its practical purpose is well known—it was used primarily to keep the herds quiet at night, for often a ballad sung loudly and continuously enough might prevent a stampede. However, the cowboy also sang because he liked to sing.... In this music of the range and trail is “the grayness of the prairies, the mournful minor note of a Texas norther, and a rhythm that fits the gait of the cowboy’s pony.””
—Administration in the State of Texa, U.S. public relief program (1935-1943)
“but we wish the river had another shore,
some further range of delectable mountains,”
—Robert Lowell (1917–1977)
“Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.”
—Walt Whitman (1819–1892)
