The drive behind a massive water development project in southwestern Utah, the Lake Powell Pipeline, shows no signs of slowing even after the Colorado River Basin states signed a new agreement this spring that could potentially force more conservation or cutbacks. Despite the risk that the river resource is overcommitted and it is shrinking, four Upper Basin states — Utah, Wyoming, Colorado and New Mexico — are pushing forward with dams, reservoir expansions and pipelines like the one at Lake Powell that will allow them to capture what they were promised under the 1922 Colorado River Compact. The Lower Basin states of Arizona, Nevada and California have been using that water downstream for nearly a century.
