This model archive summary (MAS) document and model calibration dataset describes a surrogate model used to compute suspended sediment concentrations at USGS streamgage 11509500 for water years 2019-2024. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (OWQ) technical memoranda 2016.07 (https://water.usgs.gov/osw/pubs/memo...

This data release contains a dataset of continuous in-situ water temperature records from multiple federal, state, local agencies, non-profit organizations, and private industry partners across 788 locations within the Willamette River Basin (WRB) from years 2011 to 2024. This dataset complements and extends the existing multi-agency NorWeST water temperature dataset for the Willamette...

This metadata record describes a series of datasets containing metrics used to characterize drought for groundwater wells in the conterminous United States (CONUS). This data is associated with a publication that looks to answer questions about groundwater drought in CONUS. The publication uses the time periods 1981-2020 and 2001-2020, but this dataset includes additional time periods...

Topographic data were collected along select erosional features within or adjacent to channels exposed in Fern Ridge Lake, Oregon, in 2023 and 2024 during low pool. Measurements were focused on features that displayed evidence of past or ongoing fluvial erosion and included landforms such as rills, gulleys and channel segments with knickpoints. The survey data were collected during...

In cooperation with the U.S. Army Corps of Engineers (USACE), the U.S. Geological Survey (USGS) surveyed ground control points and coordinated aerial photograph acquisition of Cougar Reservoir, a multi-purpose reservoir in western Oregon impounded by the 158-meter ([m]; 518-foot [ft]) tall Cougar Dam. Aerial photographs were acquired by the Civil Air Patrol (CAP) in December 2023 when...

In cooperation with the U.S. Army Corps of Engineers (USACE), the U.S. Geological Survey (USGS) surveyed ground control points and coordinated aerial photograph acquisition of Hills Creek Lake, a multi-purpose reservoir in western Oregon impounded by the 92-meter ([m]; 302-foot [ft]) tall Hills Creek Dam. Aerial photographs were acquired by the Civil Air Patrol (CAP) on December 20, 2023...

In cooperation with the U.S. Army Corps of Engineers (USACE), the U.S. Geological Survey (USGS) surveyed ground control points and coordinated aerial photograph acquisition of Cottage Grove Lake, a multi-purpose reservoir in western Oregon impounded by the 29-meter ([m]; 95-foot [ft]) tall Cottage Grove Dam. Aerial photographs were acquired by the Civil Air Patrol (CAP) in December 2023...

In cooperation with the U.S. Army Corps of Engineers (USACE), the U.S. Geological Survey (USGS) surveyed ground control points and coordinated aerial photograph acquisition of Dorena Lake, a multi-purpose reservoir in western Oregon impounded by the 44-meter ([m]; 144-foot [ft]) tall Dorena Dam. Aerial photographs were acquired by the Civil Air Patrol (CAP) in December 2023 when water...

The Willamette River Basin encompasses 31,000 square kilometers of western Oregon and consists of twelve major subbasins, each with hundreds of individual streams and unique hydrogeomorphic regimes and river corridor conditions. In conjunction with environmental DNA (eDNA) sample collection to support occupancy modeling of native freshwater mussels across the Willamette River Basin, bed...

Elevation-at-refusal (EAR) data were collected in May and September 2016 in conjunction with a comprehensive bed-elevation survey (White, 2025; methods described in White and others, 2025) to estimate the depth and total volume of sediment stored in a beaver pond along Fanno Creek, western Oregon. The EAR.csv file consists of points with xy coordinate and z elevation data. A stadia rod...

Base flow, the groundwater contribution to streamflow, is beneficial data for analysis of groundwater-flow systems. This data release includes base-flow estimates and streamflow data for 471 Oregon streamgage sites. Categories of data include: (1) site information, (2) water year estimates of base flow and streamflow, and (3) daily estimates of base flow. Water-year base-flow estimates...

This data release contains field and geochemical data, discharge measurements, and descriptive observations for 261 springs in eastern Oregon and northern Nevada. Data were collected during water years 2016–2023. The data release also includes quality assurance analyses and the results of a logistic model documented in the accompanying study report (Johnson, in review).
