-72® is gone. If water and power committments prevent the reservoir level from rising above the 5,871 elevation in 1963, the spring run-off in 1964 should raise it to the full elevation mark, 6,040 feet. Assuming that the projected plan of reservoir operation is followed, or a plan similar to it9 and that the practical minimum level or a level close to it is reached during drawdown, three of the proposed access sites may be unavaila~rle for boat launching purposes from the disappearance of ice cover until sufficient water is accumulated to raise the .water level to these facilities, These sites are: Y,ucerne Valley, Antelope Flats and Sheep Creek. Consequently, early spring fishermen, residents in most cases, will be forced to rely upon the remaining sites. Of the four remaining sites, Holmes Ferry and l~darsh Creek offer easiest accessibility because of their geaidents. SEIDSRADEE PROJECT Development of the Seedskadee will present a definite limitation to the fisheries potential in the Green River from the backwaters of the Flaming Gorge Reservoir to the Fontenelle Dam. The effect of the Seedskadee Project on the Green River will be: (1) Inundation of approximately 16 miles of the Green River proper, This section produces very little in the--way of sport fishing at the present time, but is potentially an excellent .site for eventual development of a good trout fishery. (2} Alteration of normal stream flow rates. - Storage of run-off water and diversion of the Green River onto irrigated lands will change normal flow rates below Fontenelle Dam. There are indications that the river bed will be completely de-watered during the latter part of the irrigating season for the months of August and September. This condition will exist from the damsite downstream to a point where waste and seepage waters are returned through drainage instal- lation in sufficient quantities to create a stream flow. (3) Increased water temperatures. - Diversion of large volumes of the Green River onto irrigated fields will expose it to warm air temper- atures and the sun. Return of this water through proposed drainage facilities will cause a temperature rise in water in the river channel, Temperatures taken at the town of Green River in 1958 showed a peak temperature of 79~ F. during the month of July under normal flow conditions. This temperature if prolonged or increased for any length of time would very likely eliminate any trout populations in this section of the river. (4) Increased total dissolved solids. - The drainage installations re- commended for the Seedskadee Project are to carry irrigation waste and seepage water back into the river. Under this drainage system, salts that might have been deposited in lower sections of the land will be carried directly into the river channel. These .salt con- centrations are expected to be quite high initially. Reduction in concentrations will depend on irrigation practices. Heavy applications
