Sonoran Desert, Chihuahuan Desert, and Southern Plains Networks Groundwater Monitoring Protocol SOP #3: Measuring Depth to Groundwater by Electric or Steel Tape (version 1.1) provides step-by-step instructions on manual methods for measuring the depth to water (DTW) in a well using an electric water level sounder or a graduated steel tape. The Sonoran Desert, Chihuahuan Desert, and Southern Plains networks make almost exclusive use of calibrated electric water level sounder methods for measuring depth to water in wells. However, in some areas, the use of steel tapes is sometimes used. Guidelines provided here closely follow procedures and guidelines provided in Groundwater Technical Procedures of the U.S. Geological Survey (Cunningham and Schalk 2011), and that document should be referred to for further details as needed.
