However, not all the water in Lake Mead comes from the Colorado River. Flowing from the north, the Virgin and Muddy Rivers converge in the lake’s Overton Arm. Another water source arrives from the west, where the Las Vegas Wash carries urban runoff, storm water and reclaimed water from the Las Vegas Valley into Lake Mead. For most of the year, the Virgin River, Muddy River, and Las Vegas Wash contribute a mere three percent of Lake Mead’s water. But during intense floods, these water sources surge, and for short periods their flow into the lake can even top that of the mighty Colorado River.
