Colorado Basin Growth The Colorado Basin is comprised of all or part of six counties. Changes in population from 2000 to 2030, including percent annual growth rate on a county level, are shown in the table here. During that time, the population in the basin is expected to grow by almost a quarter million people, or 99 percent.

M&I is defined as all of the water use of a typical municipal system, including residential, commercial, industrial, irrigation, and firefighting. Large industrial water users that have their own water supplies or lease raw water from others are described as SSI water users. M&I and SSI water demand forecasts for the Colorado Basin are shown in the table above. The 2000 and 2030 gross demands are also presented in the table along with the projected conservation savings. Conservation practices include ordinances and standards that improve the overall efficiency of water use, such as installation of low water-use plumbing fixtures. As the table indicates, the Colorado Basin will need an additional 6 1,900 AF to meet the increased demands of M&I water use. The majority of the demand is expected to be met through existing supplies and water rights and through the implementation of various projects and processes. However, there are still some anticipated shortfalls expected in certain portions of the basin. This is also shown in the table. Wet and Dry Periods Every year, there is at least one lOa-year flood somewhere in the state. Colorado's total flood losses to date have been documented to be $4.9 billion. The Colorado Basin's most recent flood event was June 1995. The estimated total historic damages for this basin are $ 109.5 million to date. - - Dry Avg Wet [ .=- 00 <0 <0 (!)
