Willamette River in Portland Water-Quality Site

Willamette River at Portland, OR, is one of the most extensively monitoring streams in the US. The monitor located at the Morrsion Bridge in downtown Portland measures thirteen real-time parameters.

Using High-Throughput DNA Sequencing, Genetic Fingerprinting, and Quantitative PCR as Tools for Monitoring Bloom-Forming and Toxigenic Cyanobacteria in Upper Klamath Lake, Oregon, 2013 and 2014

Monitoring the community structure and metabolic activities of cyanobacterial blooms in Upper Klamath Lake, Oregon, is critical to lake management because these blooms degrade water quality and produce toxic microcystins that are harmful to humans, domestic animals, and wildlife. Genetic tools, such as DNA fingerprinting by terminal restriction fragment length polymorphism (T-RFLP) analysis, high-

Beaver dam locations and beaver activity in the Tualatin Basin, Oregon, between 2013 and 2016

USGS met with 13 local groups and organizations around the Portland, Oregon region to collect information regarding the locations of beaver dams in the Tualatin Basin. The local sources had identified beaver dams between 2013 and 2016, and data were compiled by USGS into an ArcGIS shapefile. Often, the local groups did not know the GPS coordinates of beaver dams, but they had identified beaver-aff

Upper Klamath and Agency Lakes May/June 1996 bathymetric mapping project

Bathymetric data were collected over all boatable areas of Upper Klamath and Agency Lakes, located in South-Central Oregon, in May and June of 1996. Areas that were too shallow (less than 1.2m) and/or covered with aquatic vegetation were not mapped. A 21ft tunnel-hull boat was fitted with an adjustable transducer mount on the stern. The transducer was mounted on the starboard side of the prop to m

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.

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 kinematic

Flood inundation mapping data for Johnson Creek near Sycamore, Oregon

The basis for these features is U.S. Geological Survey Scientific Investigations Report 2017-5024 Flood Inundation Mapping Data for Johnson Creek near Sycamore, Oregon. The domain of the HEC-RAS hydraulic model is a 12.9-mile reach of Johnson Creek from just upstream of SE 174th Avenue in Portland, Oregon, to its confluence with the Willamette River. Some of the hydraulics used in the model were t

Boat-based river bathymetry and stream velocity on the upper Willamette River, Oregon, Spring 2015

River bathymetry and stream velocity measurements were collected in March 2015 along the upper Willamette River, Oregon, between Eugene and Corvallis. These surveys were collected over a small range of discharges using a real time kinematic global positioning system (RTK-GPS) and acoustic Doppler current profiler (ADCP) on a motorboat while transecting at various cross sections along the river.
