Lake Powell in Southern Utah is an awe-inspiring location. The lake is a reservoir created by the Glen Canyon Dam and is the second-largest man-made reservoir in the United States after Lake Mead in Nevada. Construction of the dam started in 1960 and it was dedicated in 1966. The high water mark was reached in 1980. Lake Powell features what is called a bathtub ring, which can clearly be seen on the picture to the right. This ring shows how high the water has been, at an elevation of about 1128 meters. The lowest elevation since this high water level has been in 2005 at about 1080 meters. Depending on rainfall and snow melt, this change in elevation can make every visit to the lake a new and unique experience. Aerial or satellite images show the size of the lake, but at least to me, it is a lot more impressive to see the height of the canyon walls in person. Short of seeing the lake in person, a picture of the canyon wall together with a motor boat exemplifies the dimensions. Pleasure boaters who rent or own boats embark from one of the marinas and spend most of the day driving up and down the lake and can find one of the many secluded anchor spots for the night.
The picture was taken from top of our rented houseboat with my Canon EOS Digital Rebel on May 27, 2007, using a Canon EF 28-135 ƒ/3.5-5.6 IS USM lens. The exposure was 1/300 second at an aperture of ƒ/11 and the ISO set to 100.
