-21- The river between Stations No. 5 and No. 6 is quite slow and turbid. Large areas of the stream bed are covered with shifting beds of silt and sand. The river has cut into the surrounding hills in many places, creating steep or precipitous banks composed of sandstone, clay, and a highly erosive sandy loam. Cover through this area is light. Sagebrush dominates the hillside vegetation, and sagebrush and greasewood grow together on the bottom lands. The sandbar willow is dominate along the stream banks. Some groves of cottonwood trees are found, but they are not as prevalent through this area. Occasional salt cedars are found along the river bank. :Y' _ ,. . c.` :~ii- ~ .. ---~- , ~ ~t r-..3;~ - ..-. =yaw, ~~ x ~ .. 4J ~_ F --. _ --__ _ Typical Landscape Between Stations No. 5 and No. 6 Tributary streams entering the Green River between Stations No. 5 and No. 6 are: Sage Creek, Currant Creek and the Black's Fork River. Sage and Currant Creeks are the smaller of the three, entering on the east side of the Green River. Both streams contribute large amounts of silt to the Green River during spring run-off. Diversions, for purposes of irrigation, often drastically reduce, or eliminate, water flows in the vicinity of the mouths of these streams during summer months. The beds of these streams, near their mouths, is a com- bination of shifting silt and hardpan. Currant Creek does support trout pop- ulations in its headwaters, but-none were found in the vicinity of its mouth. The Black's Fork River varies in flow rate from 3,000 cfs during run- off to 0 cfs in the late summer. The majority of the water is diverted for irrigation above Lyman, Wyoming.
