"As far as future water supplies go, the outlook is not good," says Barringer. "Most Colorado River water is currently used for agriculture, but that is beginning to shift as the cities of the Southwest continue to grow." The basin is next to fall victim to America's water crisis as the demand for water exceeds supply, and the effects of climate change could bring less rain to the region. The Bureau of Reclamation has been considering traditional solutions to the water shortage including "decreasing demand through conservation and increasing supply through reuse or desalination projects," but "a more extreme and contentious approach" is the building of a 600-mile pipeline from the Missouri River to Denver that would provide water as needed and store the remaining in reservoirs. Experts say "the plan is reminiscent of those proposed in the middle of the last century, when grand and exorbitant federal water projects were common place — and not, with the benefit of hindsight, always advisable," which shows just how serious the problem has become for the Colorado River.
The pipeline would provide the Colorado River with 600,000 acre-feet of water annually from the Missouri and Missippi River systems, enough to serve roughly a million single-family homes, but the loss of water from those rivers would likely face strong opposition from the affected states. The project would also require local taxpayers and utility customers to shoulder the costs of the project, which could cost billions of dollars. The proposal "shows you the degree to which water-short entities in the Colorado River basin are willing to go to get water" from somewhere elsewhere, said Burke W. Griggs, the counsel for the Kansas Agriculture Department's division of water resources. If the Colorado River cannot supply enough water, the fear is that water wars could restart as states fight over dwindling water sources. Jason Bane of Western Resource Advocates described the pipeline idea as "fundamentally 20th-century water-policy thinking that doesn't work in the 21st century" and said, "We clearly need to conserve and be more efficient with the water we have."
