<br />Basin Growth
<br />
<br />The Yampa/White/Green
<br />Basin is comprised of all or
<br />part of three counties.
<br />Changes in population from
<br />2000 to 2030, including
<br />percent annual growth rate
<br />on a county level, are shown
<br />in the table here. During that
<br />time, the population in the basin is expected to grow
<br />by 22, I 00 people, or 56 percent.

<br />Yampa/White/Green Yampa/White/Green Basin Demand Projections
<br />Basin Water
<br />Demands
<br />
<br />The Yampa/White/Green
<br />Basin is projected to increase
<br />in municipal and industrial
<br />(M&I) and self-supplied
<br />industrial (SSI) water demand
<br />by 22,300 acre-feet (AF) by
<br />2030. M&I is defined as all of
<br />the water use of a typical
<br />municipal system, including residential,
<br />commercial, industrial, irrigation, and firefighting.
<br />Large industrial water users that have their own
<br />water supplies or lease raw water from others are
<br />described as SSI water users. M&I and SSI water
<br />demand forecasts for the Yampa/White/Green
<br />Basin are shown in the table above.

<br />Yampa/White/Green River Basin
<br />
<br />Wet and Dry Periods
<br />
<br />Every year, there is at least one lOa-year flood
<br />somewhere in the state. Colorado's total flood losses
<br />to date have been documented to be $4.9 billion.
<br />The Yampa/White/Green Basin's most recent flood
<br />event was May 30-June 5, 1997. The estimated total
<br />historic flood damages for this basin have been $5.5
<br />million to date.

<br />
<br />The 2000 and 2030 gross demands are presented
<br />in the table along with the projected conservation
<br />savings. Conservation practices include ordinances
<br />and standards that improve the overall efficiency of
<br />water use, such as installation of low water-use
<br />plumbing fixtures. As the table indicates, the
<br />Yampa/White/Green Basin will need an additional
<br />22,300 AF to meet the increased demands of M&I
<br />water use. The majority of the demand is expected
<br />to be met through existing supplies and water
<br />rights and through the implementation of various
<br />projects and processes.
