Data

We collect data from Oregon lakes and streams, groundwater, landscapes, and ecosystems. You can access the data we've collected through the "Oregon Water Data" and "National Water Data Mapper" links below. Our data is also available from our Oregon Monthly Water Availability Report and the National Water Dashboard.

Phytoplankton Data for Malheur Lake, Oregon, 2018-2020

Malheur Lake is a shallow, freshwater lake in southeastern Oregon. This data release includes phytoplankton data from three sites located in Malheur Lake collected from 8/8/2018 to 8/11/2020. For each sample collected, the phytoplankton were reported to the lowest taxonomic unit. Phytoplankton biovolume, algal cell concentration, and algal biomass concentration are included. All phytoplankton data

Klamath Marsh January Through May Maximum Surface Water Extent, 1985-2021

The U.S. Geological Survey Oregon Water Science Center, in cooperation with The Klamath Tribes initiated a project to understand changes in the surface-water extent 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

Surficial and subsurface grain-size data for the Siletz River, Oregon, 2017-18

The Siletz River Basin encompasses 970 square kilometers of western Oregon and drains to the Pacific Ocean. In cooperation with the Confederated Tribes of the Siletz Indians of Oregon (CTSI), the U.S. Geological Survey is evaluating how streamflow and bedload sediment conditions may influence mainstem spawning habitats for spring Chinook Salmon (Oncorhynchus tshawytschya) and Pacific Lamprey (Ento

Active channel mapping for the Siletz River, Oregon, 1939 to 2016

The Siletz River Basin encompasses 970 square kilometers of western Oregon and drains to the Pacific Ocean. In cooperation with the Confederated Tribes of the Siletz Indians of Oregon (CTSI), the U.S. Geological Survey is evaluating how streamflow and bedload sediment conditions may influence mainstem spawning habitats for spring Chinook Salmon (Oncorhynchus tshawytschya) and Pacific Lamprey (Ento

Surface-water transfers and removals in the Pacific drainages of the United States

This data release contains a comprehensive, spatially referenced database of surface-water transfer and removal events in the Pacific drainages of the United States, which include the Columbia River basin, the Puget Sound basin, the coastal drainages of Washington, Oregon, and California, and the Central Valley of California. The database also includes mean annual estimates of the water diverted a

Historical streamflow and stage data for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California

The U.S. Geological Survey (USGS) compiled data from a variety of national and state agencies to create a comprehensive dataset of streamflow and stage for the lower Columbia River basin and the coasts of Washington, Oregon, and northern California. Seasonal maximum values were calculated for streamflow and stage for the winter (November-March) and spring (April-July) flow seasons, as well as for

Model Archive Summary for acoustic derived suspended-sediment concentration at 14144700 Columbia River at Vancouver, WA

Model archive summary describing the development of an acoustic derived suspended sediment time series computation model. The model archive summary describes the methods and techniques used to develop the model for the Columbia River at Vancouver site - USGS site ID# 14144700. The time series suspended sediment data will help determine the suspended sediment concentration at the site in real-tim

Reach-scale estimates of nutrient, water use, dissolved oxygen, and pH conditions in the Pacific drainages of the United States

This data release contains data sets that describe reach-scale water-quality conditions for the Pacific drainages of the United States. The nutrient and water use conditions represent the predictions from recent USGS SPARROW (Spatially Related Regression on Watershed Attributes) modeling as well as other watershed attributes. The SPARROW predictions and other watershed attributes were also used as

Water temperature data to support effectiveness monitoring of channel and floodplain restoration projects along the Willamette River, Oregon

Continuous water-temperature data were collected at multiple sites along the Middle Fork and mainstem Willamette Rivers between Jasper and Newberg, Oregon, to support effectiveness monitoring for a large-scale channel and floodplain restoration program (Willamette Focused Investment Partnership, WFIP). Continuous water temperature loggers were deployed at a subset of WFIP restoration sites where r

Mean seasonal SPARROW model inputs and simulated nitrogen and phosphorus loads for the Northeastern United States 2002 base year

This U.S. Geological Survey (USGS) data release includes input and output tabular files associated with mean seasonal 2002 simulations of total nitrogen and total phosphorus loads of the northeastern United States. The mean seasonal (MS) simulations are performed using a dynamic configuration of the USGS's Spatially Referenced Regression On Watershed attributes (dynamicSPARROW-MS) model, nonlinear
