Discrete groundwater and lake depth-to-water check-measurement data, Upper Klamath Lake, Oregon, 2017

Ten groundwater piezometers and lake-level stilling wells were deployed in Upper Klamath Lake (UKL), Oregon during May through October 2017. Piezometers and stilling wells were deployed in pairs so that water levels could be measured relative to a common measuring point (MP) at each location. Piezometers were installed in the lakebed sediment, with screens from 3.92 to 4.92 feet below the sediment-water interface (lakebed). Stilling wells were screened open to the lake. Discrete depth-to-water check measurements were collected at all ten locations at about two-week intervals using a calibrated electric water-level tape.
