The Lower Las Vegas Wash (Wash) is the ultimate 4-mile drainage segment of the Las Vegas Wash, which connects the Las Vegas Metropolitan area eastward to the Lake Mead reservoir. Lake Mead water surface elevation has been lowering over the past decades, increasingly exposing the Wash bottom with an unstable slope. This has significantly intensified erosion along the Wash, transferring an estimated 800 tons of sediments to Lake Mead daily. Increasingly impervious urban areas, climate change, and tropical storms are expected to further intensify erosion. To stabilize the Wash, the Southern Nevada Water Authority has initiated a program to design and implement additional erosion control measures along the Wash to prevent erosion against the 100-year design flow. This multi-disciplinary program includes hydrology, hydraulics, geotechnical and structural elements, permitting, sediment, water quality, etc. This presentation provides an overview of the program, challenges encountered, and proposed solutions.
