<br />f)'" (','i <br />'w t .... <br /> <br />Plan of Development <br /> <br />The reservoir area would be cleared to Bureau of Reclamation <br />standards and criteria, modified to the extent practicable to reflect <br />the recommendations of Federal and State agencies concerned with <br />recreation and fish and wildlife development. Reservoir rights-of- <br />way would be fenced to the extent needed for proper management and to <br />fulfill recreation and fish and wildlife requirements. <br /> <br />A one-family dwelling would be provided at the dam for the <br />reservoir superintendent. A garage and shop would be located near <br />the house. Facilities would be installed to measure reservoir inflow <br />and outflow. <br /> <br />CONSTRUCTION MATERIALS <br /> <br />Suitable materials for impervious and pervious embankment and <br />the downstJ~am blanket of topsoil are available in the vicinity of <br />the dams i te . <br /> <br />Coarse pervious material for the gravel blanket under the riprap <br />is not available in the vicinity of the dam. Two sources, 11 and 13 <br />miles from the damsite, were located WhiCh, with some selection in the <br />areas, should not require processing. <br /> <br />Fine concrete aggregate material is available in the flood plain <br />of the South Platte River upstream and downstream from the damsite. <br />Satisfactory sources of coarse aggregaioe material were located at <br />Greeley, Colo.; and along Clear Creek between Golden and Denver, Colo, <br />Another source to be conSidered is at Big Springs, Nebr. <br /> <br />Three sources of riprap were considered: the Fremont Butte, <br />three to four miles northwest of Akron, Colo.; the southwest Akron <br />area, eight to nine miles southwest of Akron, and the Ralston 'luarry <br />near Golden; Colo. Quality-of-rock tests and haulage-cost studies <br />indicated that the Ralston quarry is preferable. <br /> <br />Suitable material for road and highway construction is available <br />in the area. Material for railroad ballast, acceptable to the Union <br />Pacific Ra:ilroad, can be obtained from their own Sherman Hill Quarry <br />in Wyoming, 126 miles from Fort Morgan, Colo. <br /> <br />21 <br />
