Show ( 2) Streams Streamflow reductions significantly below normal annual patterns would produce unattractive, relatively empty stream channels. This problem would be most serious during the late summer and fall seasons when reservoir spills would be at a minimum. The Strawberry River, below Soldier Creek Dam, would be undesirably low for most of the year because downstream water needs would only require small releases and the planned fishery bypass would be small. ( 3) Roads Construction, improvement, and relocation of approximately 130 miles of road would cause disturbance of about 1,000 acres of land ( Refer to Table C- 2). There would be significant, permanent scarring of the natural landscape, particularly associated with the roadwork along the Strawberry Aqueduct and the Diamond Fork Power System where physiography is steep and existing vegetative ecosystems are relatively fragile. These more rugged areas would not be conducive to successful restoration treatment through contouring and revegetattng the disrupted terrain. Thus, esthetic degradation of the environment along Unit roads would be expected to be substantial in the steep, forested locations and mild in the more level areas. ( 4) Material Disposal Disposal of excess material from about 250 miles of tunnel, pipeline and canals would present a serious environmental problem having significant esthetic implications. Esthetic deterioration would be most apparent and most permanent in the mountainous sites along the Strawberry Aqueduct and the Diamond Fork Power System where the volume of material would be substantial and level disposal areas scarce. The volume of tunnel waste material that would be produced is indicated on Table C- 22. The waste material itself would not be expected to be suitable 363 |
