Thalweg determination for three rivers in the Pacific Northwest, USA, 2023 Thalweg determination for three rivers in the Pacific Northwest, USA, 2023
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...
2021 McKenzie River Topobathymetric Lidar Validation - USGS Field Survey Data 2021 McKenzie River Topobathymetric Lidar Validation - USGS Field Survey Data
U.S. Geological Survey (USGS) scientists conducted field data collection efforts between July 19th and 31st, 2021 over a large stretch of the McKenzie River in Oregon using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topobathymetric light detection and ranging (lidar) data that was collected coincidentally between July 26th...
Comparison of environmental flow recommendations for the Willamette Basin Sustainable Rivers Program, water years 2008-2022 Comparison of environmental flow recommendations for the Willamette Basin Sustainable Rivers Program, water years 2008-2022
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...
Digital elevation model and single beam sonar data from the McKenzie River, Oregon, 2021 Digital elevation model and single beam sonar data from the McKenzie River, Oregon, 2021
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...
Two-dimensional HEC-RAS models and topo-bathymetric datasets for the Willamette River, Oregon Two-dimensional HEC-RAS models and topo-bathymetric datasets for the Willamette River, Oregon
This dataset contains two-dimensional hydraulic models throughout the Willamette River, extending from the McKenzie River confluence, near Eugene, to the city of Newberg. The study reach is separated into five individual models to simplify tributary inflow boundary conditions and for run-time efficiency. These models were developed to assess juvenile salmonid habitat at streamflows...
Single-beam Echosounder Bathymetry of the Willamette River, Oregon 2015-2018 Single-beam Echosounder Bathymetry of the Willamette River, Oregon 2015-2018
River bathymetry measurements were collected in 2017 and 2018 along the Willamette River, Oregon, between Eugene and Newberg. These data were collected to complement a bathymetric lidar dataset collected in 2017 for the same section of river. In many deeper segments of the river channel, bathymetric lidar did not produce measurements of river bathymetry. To fill gaps in the bathymetric...
Point measurements of temperature and water quality in main-channel and off-channel features of the Willamette River, 2015-2016 Point measurements of temperature and water quality in main-channel and off-channel features of the Willamette River, 2015-2016
Water quality point measurements were collected by the US Geological Survey within the main channel Willamette River and its off-channel features in the summer and autumn of 2015 and 2016. All measurements include location, time, temperature, and depth below water surface, while most also include specific conductivity, dissolved oxygen, and pH.

Synthesis of habitat availability and carrying capacity research to support water management decisions and enhance conditions for Pacific salmon in the Willamette River, Oregon Synthesis of habitat availability and carrying capacity research to support water management decisions and enhance conditions for Pacific salmon in the Willamette River, Oregon
Flow management is complex in the Willamette River Basin where the U.S. Army Corps of Engineers owns and operates a system of 13 dams and reservoirs (hereinafter Willamette Project), which are spread throughout three large tributaries including the Middle Fork Willamette, McKenzie, and Santiam Rivers. The primary purpose of the Willamette Project is flood-risk management, which provides...

Integrated tools for identifying optimal flow regimes and evaluating alternative minimum flows for recovering at-risk salmonids in a highly managed system Integrated tools for identifying optimal flow regimes and evaluating alternative minimum flows for recovering at-risk salmonids in a highly managed system
Water resource managers are faced with difficult decisions on how to satisfy human water needs while maintaining or restoring riverine ecosystems. Decision sciences have developed approaches and tools that can be used to break down difficult water management decisions into their component parts. An essential aspect of these approaches is the use of quantitative models to evaluate...

Soft sediment deformation in dry pyroclastic deposits at Ubehebe Crater, Death Valley, California Soft sediment deformation in dry pyroclastic deposits at Ubehebe Crater, Death Valley, California
Soft sediment deformation structures are common in fine-grained pyroclastic deposits and are often taken, along with other characteristics, to indicate that deposits were emplaced in a wet and cohesive state. At Ubehebe Crater (Death Valley, California, USA), deposits were emplaced by multiple explosions, both directly from pyroclastic surges and by rapid remobilization of fresh, fine...
