Data

The USGS has published United States water-use data every five years since 1950. To increase the temporal and spatial availability of water use estimates using nationally consistent methods, the USGS is developing national water-use models for each major water-use category. This data release publishes crop irrigation withdrawals for the conterminous United States (CONUS) that are calculated using

The Willamette Valley Project (WVP) is a system of revetments, fish hatcheries, and 13 dams in the Willamette Basin of northwestern Oregon that is operated by the U.S. Army Corps of Engineers to provide flood risk management, irrigation, power generation, water quality improvement, and recreational opportunities, among other authorized purposes. By reducing available habitat and altering the natur

A hydrodynamic, water-temperature, and water-quality model (CE-QUAL-W2; Wells, 2020) of the Link-Keno reach of the Klamath River (Oregon) was used for calendar years 2006–15 to run a series of base and recirculation scenarios. These model runs were implemented to test alternative scenarios for routing some of the Klamath Straits Drain discharge into Ady Canal. The model scenarios were configured f

Specific conductance (SC), estimated chloride (Cl), and other major ion data sets used in an analysis of the extent to which deicer applications affect groundwater quality in the Siskiyou Pass area, southwestern Oregon, 2018 to 2021. The analysis is documented in the following publication: Gingerich, S.B., Wise, D.R., and Stonewall, A.J., 2023, Assessing the effects of chloride deicer applications

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 environ

This model archive summary (MAS) is a model update to an existing log-transformed turbidity-suspended sediment concentration (SSC) regression model computing SSC for water year (WY) 2008-2017. This model supersedes all models prior to Oct 1, 2017 and includes a new model for WY 2018-2020. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (

This model archive summary (MAS) documents the revision of suspended sediment concentration (SSC) unit and daily values computed from WY 2008-2017, and the additional computation of SSC unit values from WY 2018-2020 using a new log-transformed regression model with SSC samples from the period of record at this site. The new, revised model computes SSC unit values for WY 2008-2020. This model super

In 2021, the USGS 3D Elevation Program (3DEP) funded the collection of topo-bathymetric lidar (sometimes referred to as "green lidar") on the McKenzie River, Oregon. As part of this acquisition, lidar data were collected starting on the McKenzie River below Trail Bridge Reservoir and extending downstream roughly 125 km to its confluence with the Willamette River. Bathymetric lidar produced measure

This data release contains analytical results of organohalogenated compounds and mercury in lamprey and sediment that were collected from rivers in Oregon and along the Pacific northwest coast from 2017 to 2021. In 2017, 20 lamprey were collected off the Washington and Oregon coasts by the National Oceanic and Atmospheric Administration. These ocean-caught juvenile lamprey were parasitizing target

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

The U.S. Army Corps of Engineers is considering changing the operations of Berlin Lake, Lake Milton, Michael J Kirwan Reservoir, and Mosquito Creek Lake. The lakes in this study are all reservoirs, formed by dams. These models were constructed to simulate those operations and document possible water-quality effects in the lakes, the lake outflows, and the Mahoning River downstream of the lakes. Th

The U.S. Geological Survey Oregon Water Science Center, in cooperation with The Klamath Tribes initiated a project to understand changes in surface-water prevalence of Klamath Marsh, Oregon and changes in groundwater levels within and surrounding the marsh. The initial phase of the study focused on developing datasets needed for future interpretive phases of the investigation. This data release do
