CHAPTER 2 <br /> DEVELOPMENT OF ALTERNATIVES <br /> 2.1.1.2.6 Regional Municipal and Industrial Water Supply <br /> Projected population growth within the project area will increase the demand for water,both for <br /> household use and for commercial,industrial,recreational,and community infrastructure requirements. , <br /> Dombusch(1999)displays how population in the three-county area(La Plata and Montezuma Counties <br /> in Colorado and San Juan County in New Mexico)has changed between 1970 and 1998. La Plata <br /> County population doubled in that time period, and the population of Montezuma and San Juan Counties <br /> has nearly doubled. Figure 2-1 graphically depicts this information. The regional water use is computed <br /> from the population growth using the nationwide average domestic water use of 179 gallons per capita <br /> per day. - <br /> Figure 2-1.

For example,the Ute Mountain Ute Tribe could elect to negotiate <br /> lease terms to release water into the Dolores River to benefit fisheries. <br /> 2.1.1.3 Summary of Municipal and Industrial Water Uses by Colorado Ute Tribes <br /> and Other ALP Project Beneficiaries <br /> Table 2-2 contains a summary of projected M&I water uses and depletions by the Colorado Ute Tribes <br /> and other ALP Project beneficiaries. <br /> 2.1 INTRODUCTION AND BACKGROUND 2-8 <br />
