Louden Irrigating Canal and Reservoir Company Agenda Item 35b <br /> May 9,2014(Updated May 23,2014) <br /> Page 3 of 5 <br /> Water Rights <br /> The water rights impacted by this project include: <br /> TABLE 1: IMPACTED DIRECT FLOW WATER RIGHTS <br /> Name Amount(CFS) Appropriation Date Adjudication Date <br /> Louden Ditch 7 _ 11/10/1861 5/28/1883 <br /> Louden Ditch 40 10/1/1871 5/28/1883 <br /> Louden Ditch 123 11/1/1877 5/28/1883 <br /> TABLE 2: IMPACTED STORAGE WATER RIGHTS <br /> Name Amount(AF) Appropriation Date Adjudication Date <br /> Donath Reservoir 1,148.8 2/24/1883 5/28/1883 <br /> Rist Benson Reservoir 373.8 4/26/1903 6/29/1916 <br /> Rist Benson Reservoir 117.6 12/31/1930 11/14/1939 <br /> On average, annual diversions of the Louden Ditch are 8,000 AF. <br /> Project Description <br /> The goal of this project is to restore the condition of the diversion dam and ditch to pre-flood <br /> conditions or better. The Company has retained the services of Telesto Solutions, who is the <br /> Company's primary engineer. <br /> Alternative 1 —No Action: This alternative is considered unacceptable. Failure to complete the <br /> restoration of the ditch would result in no future water diversions. <br /> Alternative 2—Rebuilding Collaboratively: The Company did not identify any collaboration <br /> opportunities with other water right holders. Primary damage was specific to the Company's ditch <br /> system. <br /> Selected Alternative 3—Rebuild with Improvements: The selected alternative is to reconstruct the <br /> Company's system to allow water diversions and improve the headgates. This will be done in two <br /> phases. Phase 1 includes cleaning and rebuilding the ditch and service road, and salvaging the <br /> existing headgates to ensure general operation for the 2014 irrigation season. Phase 2 will replace <br /> the existing headgates with gates that are safer, more accurate, and capable of remote operation. <br /> The company has an agriculture exemption from the Corps of Engineers. The estimated engineering <br /> and construction cost of this Alternative is $215,000 and is further broken down in Table 3: <br /> TABLE 3: PROJECT COST SUMMARY <br /> Task Cost <br /> Engineering $35,000 <br /> Phase One - Ditch Rebuild $115,000 <br /> Phase Two - Headgates $65,000 <br /> Total $215,000 <br />
