-25- Station No. 6 - Holmes Ferry This station is located at the site of the old Holmes Ferry River crossing, T15N; R108W; S27. The vegetation in the .vicinity of this station is a continuation of sagebrush and greasewood, similar to the area between Stations No. 5 and No. 5. Streamside vegetation is scant in the area; greasewood extends to the river's edge along much of the area. Small amounts of Cladophora sp. was found in the sampling area. A covering of silt was present during all sampling periods. The .sampling site was located on the west side of the river just below the ferry crossing. The bottom in this area was composed of gravel from 1 to 4 inches across. This gravel was bedded in silt and formed a very firm bottom. Diatom population was heavier at this station than at Station No. 5. Fragilaria was .very apparent; Tabellaria, Gomphonema, and Cymbella were present in much reduced numbers. Zooplankton populations were slightly higher than at Station No. 5. Rotifers were the only organisms found, with an average count of .95 organisms per liter. Bottom fauna was primarily Diptera and $phemeroptera. The number of organisms per square foot averaged less than at any other station (see Table V, page 29) . The section between Stations No. 6 and No. 7 is a continuation of highly erosive steep hills bordering the river. Sagebrush and greasewood are the dominant forms of vegetation on the hillsides,- and often extend to the river's edge. Sandbar willow is pre-sent along the river°s edge, but in decreasing amounts. The river becomes increasingly more turbid through this section, having a bed of shifting sand. At the Wyoming-Utah State line, the terrain levels out for some distance on both sides of the river. This area-will be the widest part of the Flaming Gorge Reservoir, approximately 5 miles during full stages. No tributary streams enter the-Green River through this section. Station No. 7 - Linwood Bridge This station is located approximately 300 feet below the Government Bridge crossing the Green River 4 miles east of Linwood, Utah, T3N; R21E; 528. Very little streamside vegetation is present. at this station. The river banks are either 2 to 6 feet high or slope steeply into the river. Grease- wood, sagebrush and. .sandbar willow are found along the river's edge in the mediate vicinity of the sampling site.
