Show several places. The bedding plane of the shale and steep slopes combine to increase the probability of mass movement. " f. Sixth Water Reservoir to Syar Powerplant ( Section 6) " This site is limited as far as development is concerned. Sub- surface seepage is recognized in the area. Mass wasting potential is high. Bedrock outcrops are frequent. Gullies and signs of mass wasting are also observable. The high erosive nature of this area may seriously affect the proposed development. Highly mobile material when placed in this disturbed condition will be extremely susceptible to erosion. This area is one of the most active erosion sites within watershed,,'' ™ The construction of Syar and Sixth Water Reservoirs would inundate approximately 13 and 28 acres of land, respectively. The clearing required for other construction would take about another 200 acres of land out of natural production,, Some of this area presently constitutes deer habitat as well as habitat for many other organisms. Construction activities would have direct temporary adverse affects upon plant and animal life as well as upon the esthetic value of the landscape. Machinery would cause undesirable high levels of noise and dust. Adverse visual impacts would occur as natural vegetative cover would be stripped away. Restoration of construction scars would be very difficult in some areas and impossible in others. The disruption in animal life patterns would lessen somewhat after construction ceases and operation of the system begins. The temporary blockages of migration routes by the foreign sounds and odors of construction activities would stop but the human and mechanical activities associated with maintenance and operation would continue. This disruption to bird and animal life would continue. The utilization of the new improved roadways would cause increased and more intense recreational utilization of the Diamond Fork area. Some environmental degradation as well as enhancement would result from this0 The operation of the power system would have a profound affect upon the existing streamflow regimes of Sixth Water Creek and Diamond Fork. The Forest Service report for this area ™ describes to some extent how Unit operation would alter existing stream conditions. Excerpts from the report are presented below: 255 |
