<br />CDIVI <br /> <br />Update on Statewide Water Supply Initiative <br />- Rio Grande Basin <br /> <br />impact of these changes on rural Colorado economies, and the effect on the open <br />space provided by farms and ranches, is a key challenge for all Coloradans. In other <br />areas of the state, localized decreases and increases in agricultural water use are also <br />expected. A net increase in agricultural water use may occur in the Yampa/White/ <br />Green and the San Juan/Dolores/San Miguel Basins. <br /> <br />80A> <br /> <br />10A> <br /> <br />20A> <br /> <br /> <br />o Agricultural <br />.M&I <br /> <br />oSSI <br /> <br /> <br />o Agricultural <br />.M&I <br /> <br />oSSI <br /> <br /> <br /> <br />910A> <br /> <br /> <br />2000 <br /> <br />2030 <br /> <br />Figure 2 <br />2000 and 2030 Statewide Agricultural, M&I, and SSI Demands <br /> <br />Rio Grande Background <br /> <br />With the exception of the North Platte Basin, the Rio Grande Basin will experience the <br />smallest increase in M&I and SSI water demand by 2030, or 4,300 AF. In SWSI, M&I is <br />defined as all of the water use of a typical municipal system, including residential, <br />commercial, industrial, irrigation, and firefighting. Large industrial water uses that <br />have their own water supplies or lease raw water from others are described as SSI <br />water users. For the purposes of SWSI, these regional water needs in the Rio Grande <br />Basin are evaluated on a county level. These counties are shown in Figure 3 with the <br />population increases from 2000 to 2030. Table 4 shows the total population and <br />percent increases for the counties of the Rio Grande Basin. <br /> <br />4 <br /> <br />SWSI Update - Rio Grande Basin <br />
