Lake Powell is 2nd largest man-made reservoir! A Mind Blowing View! It attracts lots tourist each year, it is in city of Page Arizona and on the Colorado River, straddling the border between Utah and Arizona, United States.
It stores 24,322,000 acre feet (3.0001×1010 m3) of water when full.
My 1st trip that I give a 5 star. Short but full of surprises of how beautiful earth is!
