The Colorado Mainstem Basin encompasses approximately 9,830 square miles. The largest cities in the basin are Grand Junction (pop. 49,422) and Glenwood Springs (pop. 8,603).
By 2050, the Colorado Basin could need between between 62,000 acre feet (AF) and 101,000 AF for new municipal and industrial (M&I) demands with passive conservation included.

Colorado Basin Roundtable (BRT) Priorities
Colorado BRT Activities and Accomplishments
- Address shortages in the headwaters area
- Look at the impacts of transbasin firming projects
- Look at compact delivery impacts to existing and future in-basin water rights
- Ensure endangered species’ needs do not negatively impact future in-basin needs
- Identify nonconsumptive needs for environmental and recreational flow
- Ensure adequate water supply for future needs:
- M&I, including energy development
For their M&I needs, the Colorado BRT is actively participating in the statewide process of gathering accurate demand data. The basin participated in gathering the most up-to-date water demand data across the basin. In addition, the Colorado BRT is currently undertaking Phase II of the Energy Water Needs Study in partnership with the Yampa/White Basin. Phase II will explore the sources for water that could support the oil shale industry.
For its nonconsumptive needs, the Colorado BRT has completed Phase I, which developed a map that reflects the areas at risk that have important environmental and/or recreational values. The BRT is currently conducting a basin-wide quantification using the Watershed Flow Evaluation Tool and validating the results with site-specific quantification.
