At Lake Mead National Recreation Area, dogs on a leash no longer than 6 feet are allowed in developed areas, on hiking trails, along many beaches, and in campgrounds and some lodging facilities. Located in southeastern Nevada and northwestern Arizona, the recreation area follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, NV and Bullhead City, AZ. It includes all of the eponymous Lake Mead as well as the smaller Lake Mohave – reservoirs on the river created by Hoover Dam and Davis Dam. Lake Mead NRA features water recreation, including boating, swimming, and fishing, on both lakes as well as the stretches of river between the lakes.
