Summary
This data set contains continuous measured groundwater and lake water-level data and continuous derived vertical hydraulic gradient (VHG) data. Water-levels were measured in paired groundwater piezometers and lake-level stilling wells with submerged pressure transducers during May through October 2017 at nine locations in Upper Klamath Lake (UKL), Oregon. Continuous water-level data was barometrically compensated, corrected for shifts, and converted to values of water level below MP using discrete depth to water-level measurements. Continuous groundwater and lake water-level data were used to calculate vertical hydraulic gradient (VHG). Any data that were determined to be unrepresentative (effects from waves or field measurements) [...]

Continuous groundwater and lake water-level data were used to calculate vertical hydraulic gradient (VHG). Any data that were determined to be unrepresentative (effects from waves or field measurements) or erroneous (logger malfunction) were discarded.

Purpose
The vertical hydraulic gradient can be used to define the direction and relative magnitude of groundwater exchange between lake and sediment. Groundwater and lake water levels were monitored across Upper Klamath Lake (UKL) during May through October 2017 so that vertical hydraulic gradient could be calculated and the temporal and spatial distribution of groundwater exchange could be analyzed. This data release accompanies the publication of the U.S. Geological Survey Open-File Report "Benthic Vertical Hydraulic Gradient Data from Upper Klamath Lake, Oregon, 2017 " by Nicholas Corson-Dosch.
