Cyanobacterial Toxin Concentrations from Solid Phase Adsorption Toxin Tracking (SPATT) Samplers, Water, and Field Water-Quality Data from Monitoring Sites on the Clinch River from 2020-2023

In cooperation with the Tennessee Wildlife Resources Agency (TWRA) and University of Tennessee Knoxville (UTK), the U.S. Geological survey (USGS) collected cyanobacterial toxin concentrations (i.e., microcystin, anatoxin, cylindrospermopsin, and saxitoxin) and water-quality field data at 4 sites on the Clinch River from November 2020 to December 2023. The goal for the sample data was to better understand the occurrence and distribution of cyanobacterial toxins in a section of the Clinch River. Sample collection was primarily during the growing season, when harmful algal blooms (HABs) are known to be most active. This data release documents the toxin concentrations and water-quality data produced from the study.
