American Rivers has labeled the lower Colorado River as America’s most endangered this year, a river which Arizona depends on. According to their study released on Tuesday, President Donald Trump’s proposed budget cuts will affect a river that provides drinking water for 30 million Americans. The lower Colorado river also irrigates fields that grow 90 percent of the nation’s winter vegetables, according to the study. The Trump Administration’s Fiscal Year 2018 Budget proposal means there could be cuts to many environmental departments.
