Lake Powell images, 1999 to 2009

NASA’s Earth Observatory has a series of images from 1999 to 2009 showing fluctuating water levels in Lake Powell in southeastern Utah. Lake Powell is formed by Glen Canyon Dam on the Colorado River in northern Arizona.

Earth Observatory has a “play” link to watch the images in played in order.

From the description at the NASA Earth Observatory site:

The Colorado River flows from the Rocky Mountains in Colorado through the southwestern United States. Along its route, the river passes through an elaborate water-management system designed to tame the yearly floods from spring snowmelt and to provide a reliable supply of water for residents as far away as California. The system is both appreciated for the water it provides and criticized for the environmental and cultural losses it has created.

Among the dams on the Colorado is Glen Canyon Dam in Arizona, which creates Lake Powell—a deep, narrow, meandering reservoir—upstream in southern Utah. In the early twenty-first century, this modern marvel of engineering faced an ancient enemy: severe, prolonged drought in the American Southwest. Combined with water withdrawals that many believe are not sustainable, the drought has taken its toll on the water level in Lake Powell over the past decade.

Grace and Peace
