Lake Powell is the second largest man-made lake in the US. It is on the Colorado River, straddling the border between Utah and Arizona (most of it, along with Rainbow Bridge, is in Utah). The reservoir is named for explorer John Wesley Powell, an American Civil War veteran who explored the river via three wooden boats in 1869.
Wahweap Marina located near Page, Arizona, is the largest marina on Lake Powell. A big, broad, scenic expanse, Wahweap Bay gives you plenty of wide-open space for waterskiing and wakeboarding, yet it also offers its share of notch canyons (such as Wiregrass Canyon, Lone Rock Canyon, and Ice Cream Canyon) that are ideal for kayaks and even paddleboards.
