<br />Statewide Water Supply Initiafive
<br />As the state's population continues to grow, additional
<br />demands will be placed upon Colorado's water supplies.
<br />To characterize recent trends and existing conditions,
<br />this section presents an overview of:
<br />^ The state's current and projected population and
<br />other key demographic factors
<br />^ The role of water in Colorado's major economic
<br />sectors
<br />^ The social setting surrounding water management
<br />^ The statewide environmental setting
<br />^ The statewide institutional and regulatory setting
<br />^ Water quality
<br />Each of these components has an important role in
<br />determining current and future water use patterns in the
<br />state. Section 3 explores some of these parameters on a
<br />more detailed, basin-by-basin basis.
<br />2.1 Colorado's Historical and
<br />Projected Demographics
<br />2.1.1 Population
<br />The State of Colorado, the 24th most populous state in
<br />the United States according to the 2000 Census, was the
<br />third fastest growing state in the nation in the 1990s,
<br />surpassed only by Nevada and Arizona. Population
<br />increases have a significant impact on water planning
<br />Table 2-1 Population Prolections bv Basin
<br />and management strategies. Accurate population
<br />estimates are critical in understanding future water
<br />demands and therefore affect the decisions involved in
<br />meeting those demands.
<br />Population projections were obtained from the Colorado
<br />Department of Local Affairs (DOLA) Colorado
<br />Demography Office. The DOLA dataset includes county
<br />population projections from 2000 to 2030 in annual
<br />increments. A complete listing of the population
<br />projections is provided in Appendix A.
<br />Some counties in Colorado cross major river basin
<br />boundaries, which required their populations to be
<br />appropriately allocated among basins. Given the
<br />reallocation of population for the multi-basin counties, the
<br />total population per basin was determined. The
<br />population projections for years 2000 and 2030, percent
<br />change over 30 years, and the annual growth rates are
<br />shown in Table 2-1 for each basin.
<br />Colorado's population is expected to increase by
<br />65 percent from over 4.3 million people to approximately
<br />7.1 million people between 2000 and 2030. Of the
<br />approximate 2.8 million population increase projected
<br />over this time frame, slightly more than 1.5 million or
<br />54 percent is due to net migration into the state. The
<br />remainder is a function of birth rates that are
<br />substantially higher than the number of deaths projected
<br />for each year (DOLA 2003).
