<br />5 <br /> <br />until October, 1994. The location of these waters in relation to the 40-year floodplain <br />will be confirmed when maps are available. <br />~ Background on Proposed Species <br />Fish species proposed for stocking include largemouth bass, bluegill, channel <br />catfish, black crappie, and walleye. All five species currently exist in the Colorado <br />~ River basin. The earliest known dates and places these species were introduced to <br />western Colorado are: largemouth bass, 1895, Lower Gunnison and <br />Colorado river; bluegill, 1917, pond near Dolores; channel catfish, 1891, Colorado <br />~ Rivers; bluegill, 1917, pond near Dolores; channel catfish, 1891, Colorado and <br />Gunnison rivers; black crappie, 1944, Yampa River backwaters; and walleye, 1950, <br />Harts Basin Reservoir on Gunnison drainage (Wiltzius 19851. <br />• Currently, reproducing populations of largemouth bass, bluegill, and black <br />crappie are found in many ponds and reservoirs in the Colorado, Yampa, and White <br />River basins of northwestern Colorado. Large, reproducing populations of channel <br />~ catfish are currently found in the Colorado, Yampa, and White rivers and in some <br />ponds and reservoirs along each of those rivers. Walleye are currently found in only <br />one water, Rifle Gap Reservoir, in the Colorado River drainage. This population of <br />~ walleyes was introduced in 1972 and is naturally recruiting. <br />Largemouth bass, bluegill, and black crappie have not established reproducing <br />populations in rivers even though many of the pond and reservoir populations of these <br />~ species have frequent access to the rivers. This evidence suggests these species are <br /> <br />
