This data release contains dissolved cyanotoxin concentrations for microcystins (MC), cylindrospermopsins (CYL), anatoxins (ATX), and saxitoxins (STX) assessed using enzyme-linked immunosorbent assays (ELISA) and liquid chromatography-mass spectrometry or tandem mass spectrometry (LC-MS and LC-MS/MS, respectively) in extracts from SPATT (n=95) and DGT samplers (n=10) deployed on three Finger Lakes (Owasco, Seneca, and Skaneateles) between June and November 2019. Relative percent contributions of microcystin congeners are also provided for samples analyzed by LC-MS and LC-MS/MS. Solid phase adsorption toxin tracking (SPATT) and diffusive gradients in thin-films (DGT) are types of passive environmental samplers containing...

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).

This data release contains the results from a study that characterized the concentration and quality of dissolved organic carbon (DOC) in the McKenzie River, a relatively pristine watershed in western Oregon, and its link to forming disinfection by-products (DBPs) in treated drinking water. The study aimed to identify the primary source(s) of DOC in source water for the Eugene Water and Electric Board’s (EWEB) conventional treatment plant on the McKenzie River near river mile 11, upstream of Hayden Bridge. The two classes of regulated compounds examined—trihalomethanes (THMs) and haloacetic acids (HAAs)—form when organic carbon in raw source water reacts with chlorine and (or) bromine during water treatment. The...

The tabular data sets and associated maps in this data release represent water-quality data that were collected between April and November of 2017 and between July and November of 2019 to describe baseline conditions prior to or sometimes following treatments using herbicides or other methods to reduce the biomass of non-native water primrose (Ludwigia) within off-channel water bodies of the Willamette River near Albany and Keizer, Oregon. The water-quality parameters measured in this study included water temperature, specific conductance, pH, dissolved oxygen, turbidity, total chlorophyll, phycocyanin (blue-green algae pigment), and fluorescing dissolved organic matter in surface water.

This data release contains plankton sampling results collected in the Willamette River in Portland, Oregon. The data release will be updated with new results as they are collected. The samples in this data release were collected at USGS stations 453027122400000 (Willamette River below the Holgate Channel), 452913122394300 (Ross Island Lagoon – Willamette River), and 453833122462700 (Willamette River at RM 1.5) between May 14 and August 14, 2024. Time-series water temperature, specific conductance, dissolved oxygen, pH, and chlorophyll and phycocyanin fluorescence data that were collected at 453027122400000 are available from the USGS National Water Information System (https://waterdata.usgs.gov/nwis).

This dataset is a collection of hyperspectral imagery profiles of 13 common algae associated with Harmful Algae Blooms (HAB). Data were retrieved from a hyperspectral microscope at, and with the cooperation of, the National Institute of Standards and Technology. Samples were collected from USGS water quality sampling efforts, and were also purchased from commercial vendors of biological materials. Data are shown in basic hyperspectral imagery form, transformed into the first derivative and corrected with a flat field algorithm to account for variations in locale lighting conditions.

Water-quality data and plankton samples were collected at multiple locations within the Fernhill Natural Treatment wetland and along the Tualatin River, located to the west of Portland, Oregon, during the summers of 2018, 2019 and 2020. Water quality parameters collected include water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll, and blue green algae. Data were collected to better understand how water discharged from the upstream natural treatment wetland (Fernhill Wetlands) affect algal species and water quality in the Tualatin River.

This dataset is a collection of hyperspectral imagery profiles of algae, many associated with Harmful Algae Blooms (HABs). Data were collected using a microscope-based hyperspectral imaging system with the cooperation of the National Institute of Standards and Technology. Samples were collected from U.S. Geological Survey (USGS) water quality sampling efforts, to include water quality parameters and algal biomass. Data are shown in basic hyperspectral imagery form, normalized to 1.

This dataset contains taxonomic and biovolume data for phytoplankton sampled from Detroit Lake, OR, in August, 2019, and August, 2020. Taxonomy is reported to the lowest possible taxonomic level along with total and percent biovolume. Surface grab samples for phytoplankton enumeration were collected with a van Dorn type sampler and then transferred into a clearn polycarbonate churn. Whole water samples were dispensed for total nutrients and phytoplankton identification and enumeration, the latter preserved with 1 percent Lugol's iodine solution. Samples were analyzed at BSA Environmental Services in Beachwood, Ohio. Cell numbers of all identified phytoplankton taxa were quantified on a per milliliter basis using...
