• <br /> TELESTO <br /> SOLUTIONS. INCORPORATED <br /> October 16, 2013 <br /> Dale A Leach,President <br /> Louden Irrigating Canal and Reservoir Company <br /> 4009 E Cty Rd 30 <br /> Fort Collins, Co 80528 <br /> Subject: Louden Irrigating Canal and Reservoir Company 2013 head gate and ditch <br /> damage inventory and Engineering repair guidance summary <br /> Dear Mr. Leach: <br /> Due to the recent flooding of the Thompson River, we have summarized currently known <br /> damages to the head gate and in the ditch from the headgate to about 3,500 feet downstream. <br /> This letter also includes engineering guidance in order to complete repairs. <br /> The Louden headgate is located near Highway 34 between North Carter Lake Road and North <br /> County Road 27, at coordinates 105° 11' 23.1792" W and 40° 25' 3.4104" N, Larimer County <br /> Township 5 North Range 70 West, Section 12. The headgate location is shown on Figure 1. <br /> Photo 1 shows the pre-flood headgate, diversion, and surrounding fill. Photo 2 was taken as the <br /> flood started when the surrounding fill is still intact. Photo 3 was taken September 16, 2013 just <br /> after the flood water receded. The intent of the damage lists and engineering guidance herein is <br /> to return the diversion,headgate, and ditch to pre-flood conditions. <br /> Damage Assessment <br /> The Louden ditch has been filled with significant amount of sand, with damage to the <br /> embankments. The embankments near the headgate have been washed away. It is possible that <br /> there is damage to the headgate structure foundations, as well as the gates themselves. Debris is <br /> currently burying the headgate,preventing a complete damage assessment of the headgate as this <br /> time. The diversion itself appears to be in working order, however a complete assessment would <br /> be done once water levels drop and mud and debris has been removed from around the structure. <br /> Based upon a field investigation on September 16, 2013 and on October 3, 2013 the following <br /> areas require repair. Quantities are estimated and were not measured in the field unless otherwise <br /> noted. Figure 1 describes the damage locations. <br /> • A 55 foot long,24 foot tall area of major erosion requiring about 500 cy of fill and rock <br /> Colorado Office(Corporate) New Mexico Office <br /> 2950 East Harmony Road,Suite 200 1303 Pope Street,Suite A <br /> Fort Collins,Colorado 80528 Silver City,New Mexico 88061 <br /> 970-484-7704/970-484-7789(FAX) 575-538-5620/575-538-5625(FAX) <br />
