M&I and SSI water demand forecasts for the Colorado Basin are shown in Table 5.
Water use can be considered both in terms of gross water needs or demands - the
total amount of water delivered to a user - and in consumptive use (CU), or the water
that will actually be consumed. The 2000 and 2030 gross demands are presented in the
table, along with projected conservation savings. Of the 61,900 AF of increased water
demands in the Colorado Basin, the majority of the demand is proposed to be met
through existing supplies and through the implementation of identified projects and
processes. However, there are still some anticipated shortfalls expected in certain
portions of the basin. This is also shown in Table 5. The identified shortfalls will be
the focus for supply alternatives developed for the basin.
