<br />M&I and SSI water demand forecasts for the South Platte Basin are shown in Table 5.
<br />Water use can be considered both in terms of gross water needs or demands - the
<br />total amount of water delivered to a user - and in consumptive use (CU), or the water
<br />that will actually be consumed. The 2000 and 2030 gross demands are presented in the
<br />table, along with the projected conservation savings. Of the 409,700 AF of increased
<br />water demands in the South Platte Basin, the majority of the demand is proposed to
<br />be met through existing supplies and water rights and through the implementation of
<br />identified projects and processes. However, there are still some anticipated shortfalls
<br />expected in certain portions of the basin. This is also shown in Table 5. The identified
<br />shortfalls will be the focus for supply alternatives developed for the basin.
