Water Current Meter

Usage conditions apply
This is a direct-reading instrument with a vertical axis and a five-bucket rotor that was said to be particularly suited for use in “the rough torrents, filled with drift of all sorts” found in Western waters. Known variously as a Bailey or a Colorado water current meter, it was designed in the late 1880s by Howard Safford Bailey, a draughtsman who worked for the Western Mathematical Instrument Co. in Denver. It resembles the form developed in the early 1880s by Edwin Nettleton, the State Engineer of Colorado.
The U.S. Irrigation Survey, a project of the U.S. Geological Survey, used several meters of this sort. The Geological Survey transferred this example to the Smithsonian in 1908. The frame is nickel-plated.
