<br />850,000 irrigated acres (344,250 ha) of prime farm land currently supporting
<br />an annual agricultural industry of over $250,000,000,00 (Fig, 6)_ The question
<br />would Seem to be: Where can new undeveloped water be found? Some of
<br />the options considered in Colorado and other western states revolve around
<br />urban and on-farm conservation practices. such as metering. lawn watering
<br />restric'ions, irrigation management scheduling, development of additional
<br />ground.water supplies, and weather modification programs which address both
<br />winter and summer cloud seeding, All of these options are to some degree
<br />currently in practice within the state and within the District service area. However I
<br />a fourth option, and one near to becoming a reality, is the diversion of additional
<br />undeveloped Colorado River water from the Colorado Basin, Ibroush new
<br />diversion facilities BDd utilization of unused capacity in the exis'ing Colorado-Big
<br />Thompson Project facilities, A new project, known as the Windy Gap Project,

<br />will develop appro~imately 50,000 acre-ft (61,700,000 m ') of new water annually
<br />from the Colorado River Basin at a capital Cost of approximately $700,00 per
<br />acre-ft, This is considerably less expensive than the purchase of agricultural
<br />water currently selling for approximately $3,000,00 per acre-ft, as indicated
<br />on Fig, 5,
<br />Currently, under Colorado's entitlement to flows of the Colorado River
<br />under the Colorado River Compact, there is approximately 1.000.000 acrc-ft
<br />(1,200,000,000 m') of undeveloped water available for beneficial use in
<br />the state (Fig, 7), The water developed by the Windy Gap Project would be a
<br />portion of lhis previously undeveloped supply, The project is heing rUlanced by
<br />five major cities and one electrical utility within tbe boundaries of tbe District,
<br />Sale of revenue bonds administered by a Municipal Subdistrict of the District will
