- 11 - <br />proposed for the east -west trending fill slopes of Dam No's. 2 and 3 for concrete paving slope <br />protection, but is not proposed for riprap or soil cement slope protection alternatives due to <br />roughness provided by the riprap and soil cement slope protection which will assist in wave <br />energy dissipation. <br />4.2.2 Inlet Canal <br />It is proposed to relocate the inlet canal with the enlargement /raising of the Julesburg storage <br />level. The inlet canal relocation site is shown on Fig. 1. It is assumed that the relocated canal <br />bottom width would be 30 feet, excavation side slopes 12:1,, and the canal lateral slope 2.5 <br />feet per mile. This relocation would shorten the canal by approximately 0.4 and 1 .2 miles <br />respectively, for a 3.5 foot and 6.5 foot water level increase, and would raise the canal bottom <br />elevation at the reservoir by approximately 3.4 and 5.6 feet, respectively, including an <br />additional 2.0 feet due to the elimination of a-Atbp structure upstream from the reservoir. The <br />operation of the canal with the water level raise alternatives would be comparable to existing <br />conditions. The material excavated from the canal excavation would be used for the <br />rehabilitation of Dam 1. Under the dam raise and canal relocation options, an outlet works <br />would be constructed in Dam 1 to deliver -water to the downstream wetlands and to supply <br />Little Jumbo Reservoir, which currently obtains its water supply out of the Julesburg inlet <br />canal. <br />4.2.3 Outlet Works <br />With a water storage level' raise of 3.5 feet or higher the outlet tower platform, catwalk and <br />gate operators would be raised to elevation 3718.5. The platform would be raised by <br />constructing a new platform similar to the existing installation on top of the existing structure. <br />It is assumed that the current intake tower would perform adequately for controlling releases <br />with the raised water level. Gate operator shafts would be extended accordingly. The catwalk <br />would be extended by constructing an earthen peninsula to the existing catwalk end. <br />2\reports \97- 1- 500.nk <br />
