i 1. Protect Historic Populations and Stable Populations. New historic l popu ations were confirmed in South Apache Creek (Leary, 1987) in the Arkansas River drainage, and in Upper Hague Creek in the South Platte River drainage (see Table 1). Tarryall Creek in the South Platte River drainage has a small greenback population that is believed to be historic. Additional genetic ' research is being conducted on this population. A site near Rollinsville, also in the South Platte River drainage, needs to be evaluated as a possible historic population. 2. E_atablish 20 stable populations. Due to funding problems, restoration projects were limited to Rocky Mountain National Park and the Rock Creek drainage above the Leadville National Fish Hatchery (NFH). In the South Platte drainage, Rocky Mountain National Park restoration projects conducted through 1990, included Lost Lake, North Fork Big Thompson River, Rusted Lake, Lower Hutcheson lake, Pear Lake, Coney Creek, Sandbeach Lake, Loomis Lake and Spruce Lake. No additional South Platte restoration projects were completed from 1991 through 1994. In the Arkansas River drainage, the occurrence of a fish disease, introduced by infected non-native salmonids, within the watershed of the Leadville NFH resulted in the removal of fish from this area in August 1990. This was ' accomplished with funding from Colorado Trout Unlimited, Texaco Foundation and with assistance from the Forest Service and Colorado Division of Wildlife. 20.'4 ha of lakes and ponds and 10.3 km of stream habitat in the Rock Creek drainage above the Leadville NFH was restocked with catchable greenbacks from the Saratoga NFH in June 1991, and immediately opened to catch-and-release fishing. No additional Arkansas restoration projects were completed from 1991 through 1994. Greenbacks are known to e ist ithi 51 t it h 1 0 x w n s es t a represent 0 ha of lakes and ponds and 144 km of stream habitat. Of the 51 sites, 29 are open to ' angling and 19 are considered to be stable (see Tables 1-4). However, the majority of the projects and 17 of the stable populations are located within the South Platte River drainage. 3. Establish Wild and Captive Broodstocks. Due to the expense of maintaining native Colorado fish in National Fish Hatcheries in Wyoming and Montana, and the limited use of these fish outside of Rocky Mountain National Park, the decision was made to abandon these stocks as soon as they could be replicated within Colorado. Activities at these hatcheries were funded by the FS and BLM, while their function was transferred to the CDOW Experimental Hatchery, Ft. Collins, Colorado. Eggs were collected from Hunters Creek, Upper Hutcheson Lake, Bear Lake and the Poudre River in 1989, from Upper Hutcheson Lake in 1990, and the South Fork of the Poudre in 1992 to begin a new CDOW South Platte broodstock at Ft. Collins. Eggs were taken from the 1989 year class in 1991, with 447 greenbacks surviving to December 1991. Malachite green could not be used to control fungus in 1992, and the entire 1989 year class of greenback broodstock was lost. Attempts were made to start a CDOW Arkansas broodstock at Ft. Collins by collecting eggs from Cascade Creek in 1991. However, the Cascade Creek egg collection was not successful. In 1992, 3,200 eggs were collected from South Apache Creek. In addition to South Apache Creek eggs, 10,000 eggs were. shipped from the Saratoga NFH to Ft. Collins in August 1992. These two groups of eggs led to the successful establishment of a Arkansas River drainage greenback broodstock. Due to problems associated with construction at the Saratoga NFH in 1992, the majority of their adult Arkansas greenback broodstock was lost, and the Saratoga program was terminated by September 1992. 59 i~
