-71- temperatures are in the range of 60° to 68® F. Temperature data, from the Intermountain Chemical .Company, and maximum~ninimum temperatures recorded at Green River indicate that water temperatures approaching 60® F. can be expected about the last week in TKay and last until the end. of August or early September. ~3) Projected reservoir operation calls for the reservoir to be filling, or nearly full, by July sa the danger of sudden drops in the reser- voir water level, which could harm spawn, is at a minimum. (4) Anticipated rough fish populations will be utilizing the same area as bass so adequate food in the form of rough fish should be available for young bass. Feeding habits of bass indicate that they become inactive in water temperatures below 50~ F. The growing season estimated from available water temperature data will be between five and six months long. The heat budget of the reservoir could possibly extend this growing season. Therefore, bass would be available to peak fishing pressures have a relatively long growing season, yet be in- active during the winter and early spring drawdown periods while in close contact with rainbow populations in the main body of the reservoir. Predation on rainbow would be less in this case with .bass populations than with pike populations. Channel Catfish - ~Ictalurus punctatus) Following construction of the Seedskadee project the Green River below the project may not contain suitable habitat for salmonid species. Silt lying on the river beds total dissolved solids and water temperatures are expected to increase. River flaws will be reduced and confined to a series of long pools connected by a series of shallow areas. Organic matter coming from the project will increase. Bureau officials anticipate that the stream bed, for some ten miles below the projects will be de-watered during the fall of most years. These .conditions would appear to favor stocking of channel catfish. Channel catfish have been present in the Green River in the vicinity of the town of Green River in past years. A report of catfish taken above the Green River in 1957 from a plant made in 1955 indicates that populations could be established in the river proper. ACCESS The prime contract on Ashley Dam of the Flaming Gorge Project calls for impounding to begin on September 1s 1962. Except for a 400 cfs. release to maintain fish populations below the dams no water releases are anticipated during the remainder of the year. Bureau officials at .Dutch Johns Utah es- timate that by the spring of 1963 the water level will have raised to the 5$866 elevation mark. This elevation will provide approximately 5$000 sur- face acres of water in the reservoir at the time ice cover goes off in April or 24ay. The majority of this water will be confined in the canyon area im- mediately above the damsite. Water depth at the damsite at this -stage of filling will be approximately 265 feet. The surface of the water will be even with the Green River Bridge crossing at Linwood, Utah. No water releases are anticipated until the reservoir is at or above the minimum pool level. The minimum pool elevation is 5$871 feet. At this elevation there will be approximately 6$000 surface acres of water in the reservoir. The minimum pool elevation should be reached quite rapidly as spring run-off will come shortly after ice cover
