Willow Beach Gauging Station, Water gauging station in Lake Mead National Recreation Area, Nevada, US

Willow Beach Gauging Station is a gauging station on the Nevada side of the Colorado River, north of Willow Beach between Lake Mead and Lake Mohave. The National Register listing covers the cables, catwalk, trail and station itself. Built in 1931, it measured the river flow downstream from Hoover Dam.

The facility was built in 1931 as part of early infrastructure planning following the construction of Hoover Dam to track water flow in this river section. It ranks among the oldest monitoring stations on this river system and documents the long history of water management in the region.

The listing covers more than the station building: the National Register entry of 21 March 1986 also names the cables, the catwalk and the trail that link the measuring point on the Nevada bank to the Arizona side. Visitors on the river pass under the suspended cables and can see the catwalk strung above the water.

The station stands on the Nevada bank of the Colorado River, north of Willow Beach between Lake Mead and Lake Mohave. Reaching it requires either a boat on the river or the tramway on the Arizona side; there is no road access. The surrounding land belongs to Lake Mead National Recreation Area, so check park rules before setting out.

The listing covers not only the gauging station but also its cables, catwalk and trail. The station sits on the Nevada bank, yet the tramway used to reach it starts on the Arizona side, so a visitor crosses the Colorado River to inspect a Nevada property.
