Colorado #1 Endangered River

The Grand Canyon stretch of the Colorado tops American Rivers' 32nd annual list of endangered rivers because of cumulative threats to scenery and spring water from commercial and residential development plans, and from a push to restart major uranium mining. The designation marks the third year in a row that all or part of the drought-sapped river has been at or near the top of the advocacy group's annual watch list of rivers it feels face potentially harmful actions or decisions in the coming year. A gondola-tramway plan that would drop up to 10,000 tourists daily a few thousand feet down to the canyon bottom on the river's south side helped push the Grand Canyon section of the Colorado to the top of this year's list.
