The Donner und Blitzen River is a snowmelt and spring-fed system that is the primary drainage for Steens Mountain in southeastern Oregon. The river flows northward through the Donner und Blitzen Valley within Malheur National Wildlife Refuge before terminating in endorheic Malheur Lake. Within the refuge, water management infrastructure diverts river flow through a network of dams and...

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 Green Peter Lake, located on the Middle Santiam River about 8 kilometers upstream of the confluence of the Middle Santiam and South Santiam Rivers in western Oregon. Green Peter Lake is a multi-purpose reservoir...

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 Lookout Point Lake, located on the Middle Fork Willamette River about 30 kilometers upstream of the confluence of the Middle Fork and mainstem Willamette River in western Oregon. Lookout Point Lake is a multi...

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 Foster Lake, located near Sweet Home and Foster, Oregon. Foster Lake is a multi-purpose reservoir impounded by the 38.4-meter ([m]; 126-foot [ft]) tall Foster Dam along the South Santiam River. Aerial photographs...

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 Detroit Lake, located on the North Santiam River about 85 kilometers upstream its confluence with the Willamette River in western Oregon. Detroit Lake is a multi-purpose reservoir impounded by the 141-meter ([m]...

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 Blue River Lake, located on Blue River about 2.5 kilometers upstream of the confluence of the Blue River and the McKenzie River in western Oregon. Blue River Lake is a multi-purpose reservoir impounded by both the...

This data release provides datasets for the conterminous United States (CONUS), characterizing rapid transitions between hydrological extremes, drought-to-flood (DtF) and flood-to-drought (FtD), over 1981–2024. The datasets include event catalogs, transition catalogs, and comparison tables used to assess prevalence, timing, rapidity, and impactfulness of hydrologic transitions and their...

This model archive summary (MAS) and associated model calibration data describes a surrogate model used to compute suspended-sediment concentrations (SSC) at USGS streamgage 11516530 from October 2023 to December 2024. The period of analysis computes SSC during the drawdown and removals of three dams upstream of the streamgage and represents novel suspended-sediment transport conditions...

The Great Basin of the Western United States hosts dozens of terminal lake systems that provide critical, abundant, and diverse ecosystems that support migratory bird species, local wildlife, and nearby communities. Water quality varies across terminal lakes in the region depending on basin geology, anthropogenic water use, climate, hydrology, and water quantity. Seasonal and long-term...

The U.S. Geological Survey (USGS) Water Mission Area (WMA) - Ecosystems Mission Area (EMA) EcoDrought project is comprised of interdisciplinary teams across the United States focused on the nexus between drought and ecosystem processes. To characterize streamflow conditions in EcoDrought study areas, gage height (stage) and water temperature data were collected using submersible pressure

In 2023, the USGS 3D Elevation Program (3DEP) funded the collection of topo-bathymetric lidar (sometimes referred to as "green lidar") in the Santiam River Basin, Oregon. As part of this acquisition, lidar data were collected on the North, Middle and South Santiam and Santiam Rivers, encompassing reaches upstream of Detroit, Green Peter and Foster Lakes on each river and extending...

Reservoir outflows and downstream water temperatures in the Willamette River Basin, Oregon, are influenced by the operation of 13 U.S. Army Corps of Engineer (USACE) dams that comprise the Willamette Valley System (WVS). CE-QUAL-W2 models have been developed to simulate water release temperatures from a subset of WVS dams, and thermal effects to downstream reaches that may result from...
