• <br /> 1.0 INTRODUCTION <br /> An extreme storm stretching from Laramie, Wyoming south to Boulder, Colorado started <br /> on September 9, 2013 and lasted through September 15, 2013. This storm system <br /> produced large-scale flooding along the Big Thompson River causing major damage <br /> along its path. During the storm, the Big Thompson River basin received 7 to 16 inches <br /> of rain. A recent study performed by Ayres and Associates in Loveland, CO, showed that <br /> the Big Thompson River, which normally flows under 100 cubic feet per second (cfs) in <br /> September, peaked at approximately 10,500 cfs at the mouth of the Big Thompson <br /> Canyon. The Louden Irrigation and Ditch Company's (Louden's) diversion structure and <br /> headgate for the Louden Ditch (Ditch)are located on the Big Thompson River(Figure 1), <br /> just east of the canyon mouth and west of Loveland. <br /> Louden was diverting water into the Ditch when the flood started. This water filled <br /> reservoirs located along the Ditch. As the flood progressed, the headgate could not be <br /> reached safely for operations. During the flood, water overtopped the headgate structure <br /> by at least 3 to 4 feet(ft), resulting in damage to the headgate and Ditch downstream. <br /> Louden engaged Telesto Solutions, Inc (Telesto)to: <br /> • Assist in the evaluation of the flood damage <br /> • Provide field engineering support for repairs <br /> • Provide guidance on permitting and funding acquisition <br /> • Oversee construction repairs <br /> • Submit a completion report to support funding and document work completed <br /> Louden set goals requiring that the Ditch be operational before the first freeze(i.e., end of <br /> construction season) so that in the spring it could deliver water to its members. Not only <br /> did the Ditch have to be operational, but it had to have capacity to carry the decreed <br /> diversion amount of 170 cfs. Louden, Telesto and John Moen's team (the contractor) <br /> worked in conjunction to meet these goals by November 30,2013. <br /> Louden Irrigating Canal and Reservoir Company 1 Telesto Solutions,Inc. <br /> r Iloudrn_duch londen_ditch prochicis'2013jloodtengwering,eclette.via2013finm_kner1zoi4olio_ den_a,_ront,vc,edirrepair%inrdda: January 2014 <br />
