The National Park Service (NPS) is committed to providing safe and responsible access to water-based recreation so that every visitor has an optimal park experience. In the interest of visitor safety, Lake Mead National Recreation Area prohibits the use of inflatable and non-inflatable devices, commonly referred to as “pool toys,” while on the water at Lake Mead. https://www.nps.gov/lake/learn/news/lake-mead-national-recreation-area-reminds-visitors-to-use-only-approved-personal-flotation-devices-when-visiting.htm
