M&I and SSI water demand forecasts for the Rio Grande 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 conservation savings. The 4,300 AF of increased water demands in
the Rio Grande Basin is proposed to be met through existing supplies and water
rights and through the implementation of identified projects and processes.
