<br />Statewide Water Supply Initiative Background
<br />The Statewide Water Supply Initiative (SWSI) has identified how much water
<br />Colorado will need to help meet the needs of its growing population. By 2030,
<br />Colorado will have an additional 2.8 million residents and a total population of
<br />7.1 million people. Most of the state's population (87 percent) will be along the Front
<br />Range from Pueblo to Weld County. However, the fastest growing areas will actually
<br />be on the West Slope in the Colorado and San Juan/Dolores /San Miguel Basins.

<br />SWSI is an 18 -month study by the Colorado Water Conservation Board (CWCB) to
<br />take a comprehensive look at how Colorado will meet its future water needs. During
<br />the 199Os, Colorado was the third fastest growing state in the nation, surpassed only
<br />by Nevada and Arizona. The recent drought also highlights the importance of
<br />understanding how Colorado will manage water during times of increased scarcity.
<br />SWSI's approach to this problem is to both develop technical data and work with local
<br />interests and water experts to obtain consensus on the issues, identify where data are
<br />missing, and to understand the obstacles to meeting our water supply needs.
<br />Working with Basin Technical Roundtables consisting of multiple interests (water
<br />providers, local governments, agricultural users, recreational interests, the
<br />environmental community, and the business sector interests) from Colorado's eight
<br />major river basins (Figure 1), SWSI is a "bottoms -up" process to make sure local
<br />expertise and knowledge is incorporated into the study findings. These roundtables
<br />have identified water supply needs ranging from ensuring that municipal and
