Data

In May and June 2023, the U.S. Geological Survey, in collaboration with the Massachusetts Office of Coastal Zone Management, collected high-resolution geophysical and seafloor sampling data, in Nantucket Sound to understand the regional geology in the vicinity of Horseshoe Shoal. Geophysical data collected include swath bathymetry, backscatter, and seismic reflection profile data. Ground...

The U.S. Geological Survey (USGS) developed high-resolution orthomosaics from natural color aerial photographs collected by the Civil Air Patrol (CAP) of the McKenzie River in the Willamette River Basin in Oregon in 2022 and 2023. Aerial photographs were collected between September 20 and September 24, 2022, and again between July 1 and July 3, from a Cessna 182 aircraft with a Waldo Air...

The U.S. Geological Survey (USGS) developed high-resolution orthomosaics from natural color aerial photographs collected by the Civil Air Patrol (CAP) of 45-60 km of the North Santiam River in the Willamette River Basin in Oregon in 2022 and 2023. Aerial photographs were collected between September 14 and September 22, 2022, from Detroit Lake to Stayton, and again between July 7 and July...

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...

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 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 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...

This data release includes rasters of riverbed grain size in select Oregon rivers where substrate size has been modeled following the approach of White and others (2025a) in which bathymetric lidar point-clouds were paired with georeferenced pebble counts to produce grain-size rasters for the Santiam River Basin (White and others, 2025b). Similar to White and others (2025b), this data...

Spawning distribution maps for Upper Willamette River (UWR) spring Chinook salmon were created for the historical period (approximately 1910-1940), and for the present-day period (2003-2023). These maps were created as a tool to visualize generalized, reach-scale patterns of spawning distribution before and after the construction of high-head dams and other large-scale anthropogenic...

This metadata record describes historical flood type classifications and causal attribution data for the FEMA-funded joint U.S. Geological Survey and U.S. Army Corps of Engineers Mixed Populations Flood Frequency Project. The data listed here include classifications of historical flood peaks based on causal mechanisms determined using manual and semi-automated methods at select locations...

This data release contains Horizontal-to-Vertical Spectral Ratio (HVSR) data collected between 2017 and 2020 from 73 locations in the area surrounding Moreau Lake, Saratoga County, New York. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and...
