Cyanotoxin concentrations in extracts from cyanobacteria colonies, plankton net tows, and Solid Phase Adsorption Toxin Tracking (SPATT) samplers in western rivers, lakes, and reservoirs, including drinking water sources in the Oregon Cascades: 2016-2020

Metadata Updated: July 6, 2024

This data release contains cyanotoxin concentrations for microcystins, cylindrospermopsins, anatoxins, and saxitoxins assessed using Enzyme-Linked Immunosorbent Assays (ELISA) on 363 samples collected from 82 surface-water sites located in the Cascade Range in Oregon, and eight sites located outside of the Oregon Cascade Range in Washington and California, during 2016-2020. Three sample types were assessed: 1) benthic colonies and mats of cyanobacteria (n=109), 2) plankton net tows (n=90), and 3) Solid Phase Adsorption Toxin Tracking samplers (SPATTs)(n=164).
