<br />Potential Changes in Irrigated Acreage by 2030
<br />
<br />By 2030, reductions in irrigated acres are expected to
<br />occur in most basins as agricultural lands are developed
<br />for M&I use and/or water is transferred from agriculture
<br />to M&I use to provide for M&I water needs.

<br />Table 5-5 provides an estimate of the range of
<br />potential changes in irrigated acres in each basin.
<br />Future changes will be impacted by many factors,
<br />including the development of additional storage to
<br />provide firm water supplies for agriculture, policies of
<br />M&I water users regarding the acquisition of
<br />agricultural water rights, M&I growth rates and the
<br />location of future growth, and whether there are cost-
<br />effective alternative sources of water to meet future
<br />M&I water needs. There could be significant
<br />additional reductions in irrigated acres beyond the
<br />estimates provided in Table 5-5 if water providers are
<br />unsuccessful in implementing their identified plans
<br />such as developing additional storage to firm existing
<br />water supplies. Figure 5-5 illustrates an estimate of
<br />potential changes statewide.
