Water-Quality Datasets from Synoptic Surveys in Nolin Lake, Kentucky, using an Autonomous Underwater Vehicle, Discrete Sampling, and Depth Profiles, August 2016

The U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers—Louisville District conducted a pilot study on the use of an autonomous underwater vehicle (AUV) for a survey of water conditions during August 2016 in a portion of Nolin Lake, Kentucky. The AUV was equipped with sensors for the continuous collection of water-quality measurements for dissolved oxygen, pH, specific conductance, temperature, turbidity, total chlorophyll, and blue-green algae concentrations. The AUV continuously collected measurements of these water-quality parameters while traveling at varied depths in a set spatial pattern within a portion of the lake. In addition to the AUV survey, discrete nutrient- and algae-related samples were collected at various points in the study area of the lake, and along depth profiles. This digital dataset contains site information and the water-quality data from the AUV surveys, the discrete sampling, and the depth profiling.
