Using methods similar to the roundabout on the north side of the river, the void at the <br /> south side of the diversion structure and the undercut diversion toe was filled with large <br /> boulders, cobble and gravel. The fill material was taken from accumulated flood deposits <br /> located along the bank of the river in the general vicinity of the diversion structure. <br /> Appendix D Photo Sets 6 and 7 show the diversion structure before and after the <br /> completed repairs. <br /> 2.3 Louden Ditch <br /> The flood caused massive sedimentation along the Ditch. This sediment mostly consisted <br /> of silt to sand extending from the headgate to approximately 3,500 ft down ditch. It was <br /> estimated that the average depth of the sediment deposition throughout the Ditch was <br /> approximately 4 ft in thickness creating nearly 11,300 cy of material that needed to be <br /> excavated and re-deposited. In multiple locations, where the pre-flood Ditch and banks <br /> were covered with sediment, the sediment was excavated until resistance was felt by the <br /> operator. This resistance generally aligned with the pre-flood ditch banks. The <br /> excavated material was placed on the south side of the Ditch along the ditch access road. <br /> The excavated sediment was used to build up the ditch road and reform the roundabout <br /> near the headgate. Appendix D Photo Set 8 shows a typical section of the Ditch before <br /> and after the completed repairs. <br /> 2.4 Ditch Access Road <br /> The ditch access road runs adjacent to the Ditch. Flood water deposited silt in the Ditch <br /> and piled debris up at the subdivision bridge and the Highway 34 bridge. The debris and <br /> sediment limited the Ditch carrying capacity. Due to the flood flows exceeding the <br /> Ditch's limited capacity, the Ditch overtopped at multiple locations. Overtopping eroded <br /> the ditch bank of the Ditch and the access road at three locations. The debris from around <br /> both bridges was removed and the sediment was excavated (Appendix D Photo Sets 9 <br /> and 10). Locations where minor overtopping but no erosion occurred, the height of the <br /> ditch road was increased using excavated ditch sediments,as described in Section 2.3. <br /> Louden Irrigating Canal and Reservoir Company 4 Telesto Solutions,Inc. <br /> r:Ilouden_dachlouden_duchlproducts12013Jloadlengureeringrecletrr111042013find lecer120140110 budenas_constructedJlood repdrJLiald January 2014 <br />
