LAKE POWELL RESORTS & MARINAS, managed by Aramark, is located in southern Utah and northern Arizona. We operate four marinas on Lake Powell and we offer great incentives for our employees to get out and enjoy the lake so if you love boating and hiking, come and enjoy nearly 2,000 miles of shoreline and the warm weather that makes this a great place to work and play! Lake Powell is the second largest man-made reservoir in the United States. 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.
