<br />non-reimbursab~e. This amount amortized in a 50-year period at 3 percent
<br />interest, is equivalent to an annual cost of ~;58,300. Forty percent of the
<br />estimated annual operation and maintenance costs of $3,400 are also a proper
<br />charge to flood control. The tota1 annual charge to flood control is,
<br />therefore. $61,700.

<br />'-.I 23. The estimat~ mean annual increase in gross crop income to the
<br />irrigators that will result with the regulation of the Conejos River flows
<br />by the 60,000 aore-foot Platoro Reservoir, considering development of the
<br />entire project area of 91,650 acres, is $1,526,000. With such a develop-
<br />ment, the annual amount available for water charges ~ the Conejos Water
<br />Conservancy District would be $0.71 per acre, or a total of :;;65,100. Should
<br />the water users elect to retire the Class 5 and 6 lands now irrigated in
<br />favor of a more complete and intensified development of Class 1, 2, and :3
<br />lands, the amount available for water charges within the District would
<br />increase materially. ConSidering the development to include only Class 1,
<br />2, and 3 landS, and assuming that desired changes in cropping praotioes ha~
<br />been obtained, the amount available for water charges may reasonabl;y be
<br />expected to be $1.71 per acre annually. The amount available f'rom the
<br />62,280 acres of Class 1, 2, and :3 lands within the District, on this basis,
<br />would then be 1;106,500 annually, The operation of the 60,000 acre-foot
<br />Platoro Reservoir will rl;lsult in an average annual reduction of 063,400 in
<br />flood damages in the Conejos area.
