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).

In May 2023, the U.S. Geological Survey provided training for bathymetric data acquisition and processing for the Iraq Ministry of Water Resources. The training included multibeam sonar theory, survey planning, data collection and processing, and dissemination. This data release presents the raw survey data, a digital elevation model (DEM), and a thalweg shapefile for three survey areas in the Pacific Northwest, USA (Mores Creek, Idaho; Columbia River, OR; Willamette River, OR). Additionally, metadata describes the processing steps, quality assurance and control, and an overall summary of each dataset. The bathymetry point cloud data were collected at selected study sites in the Pacific Northwest, U.S.A, May 2023...

In the Willamette River Basin in northwestern Oregon, stream temperature has been altered by 13 dams operated by the U.S. Army Corps of Engineers (USACE), negatively influencing threatened populations of native salmonids. CE-QUAL-W2, a two-dimensional, hydrodynamic water quality model, has been used to investigate temperature and heat patterns in the Willamette River and the downstream effects of dam operations and other anthropogenic effects on heat and stream temperature. This data release includes the input and output files for six CE-QUAL-W2 models that include Fall Creek downstream of Fall Creek Dam, the Row River downstream of Dorena Dam, the Coast Fork Willamette River downstream of Cottage Grove Dam, the...

The U.S. Army Corps of Engineers (USACE) and the Nature Conservancy developed the Sustainable Rivers Program (SRP) as a collaborative environmental flows program to identify, refine, and implement environmental strategies at select USACE dams. The SRP was introduced to the Willamette Basin, Oregon, in 2007 through a series of environmental flow workshops, which led to stakeholder generated environmental flow recommendations in the North Santiam, South Santiam, Santiam (Bach and others, 2013), McKenzie, South Fork McKenzie (Risley and others, 2010), and Middle Fork Willamette Rivers (Gregory and others, 2007, https://www.hec.usace.army.mil/sustainablerivers/). This data release is a compilation of the stakeholder-defined...

This is a spatially referenced water quality dataset for the Lower Columbia River in July 2016. The data were collected using the FLAMe water quality mapping platform having a YSI EXO2 multiparameter sonde, and an LGR greenhouse gas analyzer.
