A Measuring and Recording Device


A Measuring and Recording Device

Colorado's system of water law requires precise measurement of how much water each ditch is taking from the creek. Every ditch has a measuring device, usually a Parshall Flume, installed near its headgate. A recording device keeps track of how much water is going through the flume and down the ditch.
