<br />. <br /> <br />nn {' r. <br />(... \J .J L' <br /> <br />Fort Morgan Canal Outlet Works <br /> <br />. <br /> <br />The Fort Morgan Canal Outlet will be located about 110 feet <br />to the left of the existing Fort Morgan Canal. Construction will be <br />scheduled so that service to the existing canal below the dam will <br />not be interrupted during the irrigation seasons prior to initial <br />storage of water in the reservoir. When storage in the reservoir <br />reaches the minimum water surface elevation of 4351 feet, the <br />Fort Morgan Canal upstream from the dam will be abandoned. The <br />Fort Morgan Canal has rights to 323 second-feet of water under a <br />priority dated October 18, 1882. However, the capacity of this <br />canal is estimated to be 350 second-feet at the damsite. Since <br />flows equal to the capacity of the canal are demanded at times <br />and have been supplied from the Jackson Lake storage right, the <br />outlet is designed to carry 350 second-feet at minimum reservoir <br />water surface elevation 4351 feet with a maximum canal water <br />surface elevation of 4345 feet at the downstream end of the outlet <br />stilling basin. This criterion established the minimum operating <br />reservoir water surface elevation. The outlet works will consist of <br />an inlet structure with a trashrack, a 9' 6" concrete circular con- <br />duit, a gate chamber housing a high pressure gate, a 6-foot diameter <br />steel pipe installed inside a lO-foot diameter concrete horseshoe <br />conduit, and a control house. The steel pipe will branch at a wye <br />just ahead of the control house into two lines, with the flow <br />from each controlled by a high pressure gate. Details of this out- <br />let works are shown in exhibit 5. <br /> <br />Dikes <br /> <br />Three dikes will be required across low areas to maintain a <br />reservoir crest elevation of 4453. The dikes were designed with <br />a crest elevation of 4453, minimum crest width of 30 feet, upstream <br />slope of 2:1 protected by a 24-inch layer of riprap on a 6-inch layer <br />of gravel bedding, and a minimum downstream slope of 2:1. <br /> <br />The Riverside Dike is a 6,100-foot extension of the left <br />abutment of Narrows Dam. The dike will generally be constructed <br />in conjunction with the south bank of the existing Riverside Canal. <br />Relocated State Highway No. 144 will be on its crest. <br /> <br />The Saddle Dike will be located approximately 2,800 feet south <br />of the right abutment of Narrows Dam on its projected axis. This <br />dike across a low saddle will be 475 feet long. <br /> <br />Layton Dike will begin approximately one mile south of the <br />right abutment of Narrows Dam near the southeast end of existing <br />Bijou Reservoir No.2. This dike will extend 6,160 feet around the <br />south edge of the reservoir and north of the existing Layton Lateral. <br /> <br />. <br /> <br />22 <br />
