<br />Under 1964 Supreme Court decree accountmg, water conservation wlthm the lID that IS transferred to other
<br />Colorado River water users is still charged as a diversion by lID.
<br />
<br />III.D Future Water Requirements
<br />The determination of the current and historical water requirements of the District in Chapter
<br />III.C.5 established the foundation for projections of future water requirements for the year 2045.
<br />In the year 2045, the most probable demand scenario is based on a reduction in total farmable
<br />acres within the District to a minimum of approximately 427,600 acres (compared to 480,000
<br />farmable acres in 1994).
<br />
<br />IILD.l Future Agricultural Water Requirements
<br />As previously noted, agriculture is the largest user of water within the Imperial Valley and in the
<br />year 2045 agriculture will still be the largest user of water. Reductions in agriculture's water use
<br />will be directly related to the amount of land that is removed from cultivation due to urbanization
