Colorado River Is America's Most Endangered River, According To American Rivers Group

The Colorado River has been identified as America's most endangered river in an annual survey of the health of the nation's rivers. Demand for water from the Colorado River is outpacing the supply and a recent study by the Colorado's Bureau of Reclamation says in addition to there not being enough water in the river to meet current demands, up to a 30 percent decrease in flow by 2050 will ensure that the river will not meet future demand either.
