Data from an Analysis of Dissolved Organic Matter in the Upper Klamath River, Lost River, and Klamath Straits Drain, Oregon and California, 201316

Concentrations of particulate organic carbon (POC) and dissolved organic carbon (DOC), which together comprise total organic carbon, were measured in a reconnaissance study at sampling sites in the Upper Klamath River, Lost River, and Klamath Straits Drain in 201316. In addition, data for total nitrogen and chlorophyll a were collected. Optical absorbance and fluorescence properties of dissolved o

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
