Historically, <br />Colorado squa,,"fi~h grew to nenrly 6 feet long and more than 80 puunds and may have lived SO or more year.;. This is <br />the largest member of the minnow family. Early settlers called the fISh "white salmon" or "Colorado salmon." Colorado <br />squawlish are thooght to have evohed more that 3 million years ago. Native Color-.tdo squawflSh stocks survi~e only in <br />the Upper Basin, where their nwnbers are relatively high only in the Green and Yampa riven;. <br /> <br />Di~trihulion: <br />Colorado ~quawrlSh were once abundant in the mainstem of the Colorado River and most of its m:\ior tributaries in <br />Colorado, Wyoming, Utah, New Mexico, Arizona, Nevada. California, and Mexico. <br /> <br />Now, Ihere may be as few as 10,000 adult Colorado squawilSh in the wild. They exist primarily in the Green River <br />below the connuence with the Vamp" River below Craig, Colorado, the White River from Taylor Draw Dam near <br />Rangely duwnstre:un 10 Ihe connuence wilh the Green River, and the Colorado River from PaliSllde, Colorado, <br />downstream to Lake Powell. Hatchery reared fish have been reintroduced in Ihe Salt and Verde rivers as pan of <br />rec:o,,"ery efforts in Arizona. <br /> <br />Hahitat; <br />Colorado squawfisb spawn in white water canyons. This reproduction is associated with declining flows in June, July, or <br />August wh<n tompenlures reach about 2.1 degrees Celsius. After spawnjnJ, the adults use a variety or habitats <br />including eddies, backwaters, shorelines, and others. In spring and early summer, adults also lISe lowlands that are <br />inundated during typical spring flooding. Once the newly hatched rlSh emerge from the spawning substrales, they enter <br />the drift and are known to drift for 6 days and average distances of aboul 100 miles. <br /> <br />7 <br />
