<br /> <br />Amity Mutual Irrigation Co. <br />November 19-20. 2001 <br /> <br />Agenda Item 22d. <br /> <br />.. <br /> <br /> <br />Water Rlahts <br />The Company owns water storage rights in the Neenoshe Reservoir, as well as direct flow a. <br />rights in the Amity Canal. The Neenoshe Reservoir has a!capaclty of 60,618 ac-ft and the . <br />Company has an 1150-cfs direct flow water right in the At;nity Canal. Water rights owned by the <br />Company are shown in Table 1: . <br /> <br />Table1: Water Rights of the Amity Mutllallrrigation Company <br /> <br />Priorltv Date and Structure Storaae (Acre-feet) Direct Flow (cfs) <br />Aug 1, 1898, Great Pia ins 265,552 1150 cfs at LaJunta <br />Reservoir Svstem or 880 cfs at John Martin <br />February 21, 1887, Amity headgate N/A 283.50 cfs <br />April 1, 1893, Amitv headqate N/A ! 500 cfs <br />Totals 1933.5 cfs or 1663.5 cfs <br /> . <br /> <br />There is a one-time refill right to the Great Plains Reservoir System. Water is delivered through <br />the Fort Lyons Canal to the Kicking Bird Canal, and then to the Reservoir system. The <br />Company has diverted an average of 54,460 ac-ft over the past 10 years, according to State <br />Engineer Records. <br /> <br />Proiect DescriDtion <br />Three alternatives were analyzed in the feasibility study: <br />1. No Action <br />2. Rehabilitate the outlets and construct a new stilling basin ($400,000) <br />3. Replacement of the outlet system ($960,000) <br /> <br />Alternative 3, Replacement of the outlet system, was ruled out because it would increase the <br />cost of the project significantly with little added benefit.IAltemative 2, Rehabilitate the outlets <br />and construct a new stilling basin, was the alternative with the least overall cost that was a <br />permanent solution to the problem. This alternative is qonsidered the preferred alternative. The <br />no-action alternative was considered unacceptable sinpe it would mean that the reservoir would <br />remain restricted to gage 23.5 feet, an annual loss of approximately 8,000 ac-ft of storage. This <br />would be a significant hardship for the shareholders. <br /> <br />Selected Alternative 2 consists of relining the four outlets with 27-inch steel pipe, grouted in <br />place. New 30" by 30" sluice gates with new manual hoists will be installed on the upstream <br />headwall. The stilling basin will be demolished and rebuilt of reinforced concrete. A toe drain <br />with engineered filter will be incorporated into the stillihg basin design. <br /> <br />The implementation schedule calls for completion of financing arrangements in spring 2002. <br />Final engineering design will be completed by fall 2002. Construction will be completed in fall- <br />winter 2002. <br /> <br />Financial Analvsis <br />The total estimated cost of the project is $400,000, aM the water is used for agricultural <br />purposes. Staff is recommending a 30-year loan in rTjaximum amount of $360,000 <br />(approximately 90% of estimated project cost.) <br /> <br />2 <br /> <br />e <br /> <br />.e <br />
