Upper Klamath Basin Studies and Data Collection
The USGS has been studying the Klamath Basin for decades. The USGS provides unbiased data to Tribal partners and resource managers to aid with complex management and conservation efforts.
Malheur Lake Light Transmission Study
The Malheur National Wildlife Refuge provides habitat for a variety of highly valued ecosystem services, including shorebirds, waterfowl, and a diversity of other wildlife species.
Future Climate Effects on Columbia and Willamette River Levees
USGS research directly helps local public agencies that are responsible for the design and maintenance of the levees that surround the northern Portland metropolitan area with the goal of protecting life and property in the event of flooding from the Columbia and Willamette Rivers that surround the city.
Future Water Clarity and Dissolved Oxygen in Crater Lake
Warming air temperature may change water temperature and water column mixing in Oregon’s Crater Lake over the next several decades, potentially impacting the clarity and health of the iconic lake.
1-D Deep Ventilation (1DDV) model for Crater Lake, Oregon, 1950-2100 1-D Deep Ventilation (1DDV) model for Crater Lake, Oregon, 1950-2100
This data release contains the source code for the 1-D Deep Ventilation (1DDV) model (written in the Matlab programming language), and the input and output data from that model that were used to simulate temperature, salinity, and dissolved oxygen (DO) at specific depths in the lake. The input data consisted of: 1. daily average surface water temperature either a. collected by...
Photosynthetically Active Radiation Measurements Collected at Malheur Lake, OR, 2017-2018 Photosynthetically Active Radiation Measurements Collected at Malheur Lake, OR, 2017-2018
The USGS measured photosynthetically active radiation (PAR, wavelength between 400 and 700 nanometers) at Malheur Lake, Oregon, as vertical profiles and as continuous measurements at a fixed depth, in 2017 and 2018. Malheur Lake is a large, shallow, turbid lake located in southeastern Oregon that fluctuates widely in surface area in response to yearly precipitation and climatic cycles...
Hydrodynamic model of the lower Columbia River, Washington and Oregon, 2017-2020 Hydrodynamic model of the lower Columbia River, Washington and Oregon, 2017-2020
A three-dimensional hydrodynamic model of the lower Columbia River (LCR) was constructed using the Delft3D Flexible Mesh (DFM) modeling suite to simulate water levels, flow, and seabed stresses between January 1, 2017, and April 20, 2020. This data release describes the construction and validation of the model application and provides input files suitable to run the model on Delft3D...
Water surface elevations recorded by submerged water level loggers along the upper Deschutes River, Oregon, between Benham and Dillon Falls, Summer, 2016 Water surface elevations recorded by submerged water level loggers along the upper Deschutes River, Oregon, between Benham and Dillon Falls, Summer, 2016
Water-surface elevations were recorded by 17 submerged water level loggers between March and October, 2016 along a 3 kilometer reach of the upper Deschutes River, Oregon. 15 water level loggers were installed along the channel margins and 2 loggers were placed in off-channel wetland ponds. Submerged depths recorded at each logger were converted to water surface elevations using real-time...

Implications of water, sediment, and nutrient budgets for the restoration of a shallow, turbid lake in semiarid southeastern Oregon Implications of water, sediment, and nutrient budgets for the restoration of a shallow, turbid lake in semiarid southeastern Oregon
Malheur Lake is the largest lake in the endorheic Harney Basin in southeastern Oregon. Since the 1990s, Malheur Lake—which averages depths of about 1 meter—has been in a degraded, turbid state lacking submergent and emergent vegetation. The goals of this study were to identify the major sources of sediment and nutrients to Malheur Lake to determine the importance of managing nutrients...

Future climate-induced changes in mixing and deep oxygen content of a caldera lake with hydrothermal heat and salt inputs Future climate-induced changes in mixing and deep oxygen content of a caldera lake with hydrothermal heat and salt inputs
Vertical profiles of temperature, salinity and dissolved oxygen in Crater Lake, a caldera lake in the Oregon Cascade Range that receives hydrothermal inputs of heat and salt, were simulated with a 1-dimensional model. Twelve Global Circulation Models and two Representative Concentration Pathways (RCPs) were used to develop boundary conditions from 1950 to 2099. The model simulated the...

Light attenuation and erosion characteristics of fine sediments in a highly turbid, shallow, Great Basin Lake—Malheur Lake, Oregon, 2017–18 Light attenuation and erosion characteristics of fine sediments in a highly turbid, shallow, Great Basin Lake—Malheur Lake, Oregon, 2017–18
Malheur Lake is a large, shallow, turbid lake in southeastern Oregon that fluctuates widely in surface area in response to yearly precipitation and climatic cycles. High suspended-sediment concentrations (SSCs) likely are negatively affecting the survival of aquatic plants by reducing the intensity of solar radiation reaching the plants, thus inhibiting photosynthesis. This study was...

Use of boosted regression trees to quantify cumulative instream flow resulting from curtailment of irrigation in the Sprague River basin, Oregon Use of boosted regression trees to quantify cumulative instream flow resulting from curtailment of irrigation in the Sprague River basin, Oregon
A boosted regression trees (BRT) approach was used to estimate the amount by which streamflow is increased when irrigation is regulated (curtailed) upstream of a streamgage on the Sprague River in southern-central Oregon. The BRT approach differs from most other approaches that require baseline conditions for comparison, where those baseline conditions are determined from past...

Annual variations in microcystin occurrence in Upper Klamath Lake, Oregon, based on high-throughput DNA sequencing, qPCR, and environmental parameters Annual variations in microcystin occurrence in Upper Klamath Lake, Oregon, based on high-throughput DNA sequencing, qPCR, and environmental parameters
Cyanobacteria-dominated blooms in Upper Klamath Lake, Oregon, create poor water quality and produce microcystins that may be detrimental to local wildlife and human health. Genetic tools, including high-throughput DNA sequencing and quantitative polymerase chain reaction (qPCR), have been shown to improve the identification and quantification of key groups associated with these blooms...

Assessment of Columbia and Willamette River flood stage on the Columbia Corridor Levee System at Portland, Oregon, in a future climate Assessment of Columbia and Willamette River flood stage on the Columbia Corridor Levee System at Portland, Oregon, in a future climate
To support Levee Ready Columbia’s (LRC’s) effort to re-certify levees along the Columbia and Willamette Rivers and remain accredited, two 2-dimensional hydraulic models, Adaptive Hydraulics and Delft3D-Flexible Mesh, were used to simulate the effects of plausible extreme high water during the 2030 to 2059 period. The Columbia River was simulated from Bonneville Dam, situated at river...
