000149 A streamflow analysis was conducted to deteTmine the quantity and time of occurrence of water within the Little Snake drainage. Like most Wyoming streams, the runoff of the Little Snake River is dependent upon snowmelt runoff for its flow. Therefore, the flow of the Little Snake and its tribu- taries varies significantly with time of year. Also, the flow of the river varies, sometimes drastically, from year to year. The streamflow is further influenced by irrigation depletions and transbasin diversions. The results of the streamflow analysis are summarized in Table 1 for selected streams in the study area. Water quality in the Little Snake River drainage can generally be described as good. The runoff from high mountain streams is of exceptionally high quality, except for Haggerty Creek, Copper concentration is extremely high in Haggerty Creek, probably due to past mining activities. Overall, however, little chemical pollution is introduced into the streams. The main contribution to chemical pollution is associated with irrigation return flows (WPRS, 1977). Surface water in the project area is generally suitable for use on all adapted crops and, with primary treatment, domestic use. E. Fish and Wildlife Several species of game and nongame fish species inhabit the study area. Table 2 is a list of fish, by species, found in the study area. No threatened or endangered species inhabit the study area, However, the Colorado cutthroat trout are found in several of the high mountain streams. This species is listed as "sensitive" by the Wyoming Game and Fish Department. Nongame species i.nhabit the lower reaches of streams in the project area. Mule deer are common throughout the study area. The mule deer move into the higher elevations in July and remain there until snow forces them into lower elevatiotls in the fall. Elk are found in the study area in the eastern areas close to the Sierra Madre Mountains, The elk move into the higher eleva- III-4
