Change in Water Volume of Lakes Mead and Powell

Change in Water Volume of Lakes Mead and Powell

The filling of Lake Mead (green) was initiated in 1935, and that of Lake Powell (blue) in 1963. In 1999, the lakes were nearly full, but by 2007, the lakes had lost nearly half of their storage water after the worst drought in 100 years.  Image Reference: USBR1
