33 32 4307.0 o 17,350 o the left abutment of Narrows Dam constructed generally in conjunc- tion \\'ith the south bank of the existing Riverside Canal. Relocated State Highway t44 would be on its crest, The 475-foot-long Saddle dike would be located about one-half mile south of tbe right abutment of N arrows Dam on its projected axis, The Lal'ton dike would begin about 1 mile soutb of tbe right abutment of Narrows Dam near the southeest ed/(e of the existing Bijou Reservoir No, 2. It would extend 6,160 feet around the south edge of that reservoir and would be north of the existing Layton laieral. Electrical power for operating the facilities at the damsit.e could be supplied by either the Morgan County Rural Electric Association or the Public Service Co, of Colorado since both organizations have transmission lines in the vicinity. No arrangement has been made for service with either, but. the plan assumes that such an arrangement will be COllsummated at an appropriate time. The pla.n does provide for approximaooly three-fourths of a mile of 13,8 kilovolt line to be con- st.ructed from the point. of delivery to the outlet works and to permanent operaiing facilities. Relocations in the reservoir area would involve the main Chicago- Denver ,line of the Union Pacific Railroad, State Highway 144 a county road, power and telephone lines, oil and gas pipelines, and f\ 30-gra,e cemetery, Subject to negutiations witb tbe railroad company, it is planned to construct 32.22 miles of new line around the north side of the reservoir to replace 30,34 miles of existing railroad along the nortb bank of the river. For estimating the relocation cost, current standards of con- struction es rurnisbed by the railroad companr. were used, Credit for betterments over equivalent replacement will be obtained during negotiation, Salvage value of the old line also sbould reduce tbe total cost or the relocation. Tbe cost estimate for relocation of State Highway No, 144 reflects some impro'\""ement of the road to bring it to current standards. The addition8.l cost over that for equi,alent replacement would be $139,000, Morgan County is reconstructiug the county road to be relocated and tbe cost of relocation is based on the county standards, Tbe reservoir area. would be cleared to Bureau or Reclamation standards and criteria, modified to tbe extent practicable to reflect tbe recommendations of Federal and State agencies concerned with recreation and fisb and wildlife development, Reservoir rights-of-way would be fenced to tbe extent needed for proper management and to fullill recreation and fish and wildlife reqlllrements, A one-family dwelling would be provided at the dam for tbe reservoir superintendent, A garage and sbop would be located near the bouse, Facilities would be insta.lled to measnre reservoir inflow a.nd outflow. ~y bonsLnlCting the concrete conduits first and deferring insta.llat" ~br~u~~aZh~ and r~ellil.'e, the Fort Morgan Canal could be rou~~d r t. . con Ult unng constructIOn of the dam without inter up mg serVIce. - Exhibit -4 AREA CAPACITY DATA-NARROWS RESERVOIR,COLORADO CONTROL POINT ElEIl IN FEET ITEM INITIAL AREA IN ACRES CAPACITY acr. ,.., INITIAL lNCR~N~NT TOTAL 4453,0 "7": h:.;.:.
