Environmentalists would agree that replacing a natural condition with artificial, without disturbing the natural course is something impossible. Scientists too, are pondering on to find a solution to a similar problem. They don’t know how to protect the Colorado River in the Grand Canyon without disrupting water and power production upstream. Several natural conditions were erased by construction of Glen Canyon Dam, which supplies water and electricity to millions of people. Only a few attempts in trying to mimic the natural conditions have succeeded. Endangered fish in the river continue to disappear, habitat erodes almost as fast as it is rebuilt and interloping fish and plants find new ways to thrive. As the river courses through the Grand Canyon, its health is focused. Deteriorating conditions caused by Glen Canyon Dam are uncovered after environmental studies and a 10-year-old program is created. The giant structure cooled the river, stripped it of sediment and nutrients and tamed its seasonal flows, which helped keep wildlife habitat vital.
