Hall Water Current Meter

<< >>
While serving as California’s first State Engineer, William Hammond Hall created the Golden Gate Park in San Francisco and worked on a comprehensive water supply and flood control system for the Sacramento Valley. For this latter purpose he designed an electric water current meter similar to that developed E. E. Haskell at the U.S. Coast & Geodetic Survey. This example is 14 inches long, has two flukes, one on each side of the central axis, and is equipped for a rod suspension. It was used in the U.S. Irrigation Survey, a project of the U.S. Geological Survey begun in the late 1880s. The Geological Survey transferred it to the Smithsonian in 1916.
