Data and Tools
Biology and Ecosystems Datasets
Mapping, Remote Sensing, and Geospatial Data
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.
Stream Segments Captures and Crossings Associated With 2012 Aquatic Organism Passage Study Siuslaw National Forest
Stream segments, aquatic organism captures, stream surveys, and road-stream crossings described by these metadata accompany a 2012 electrofishing study of the distribution and abundance of aquatic organisms conducted by the U.S. Geological Survey, and the U.S. Forest.
This database is the result of an extensive literature search aimed at identifying documents relevant to the emerging field of dam removal science. In total the database contains 179 citations that contain empirical monitoring information associated with 130 different dam removals across the United States and abroad.
The online Health-Based Screening Level database contains benchmarks for over 700 contaminants. Health-Based Screening Levels (HBSLs) are non-enforceable water-quality benchmarks that can be used supplement U.S. Environmental Protection Agency Maximum Contaminant Levels and Human Health Benchmarks for Pesticides.
At this website, one can view lists of native freshwater snails by state or province boundary, and plot distributions of snails by political boundaries. Lists can be downloaded for use in reports or analyses. Data file last updated 12/17/2013.
The 2008 AFS Endangered Species Committee list of imperiled freshwater and diadromous fishes of North America
At this website, one can view lists of imperiled fishes by freshwater ecoregion, by state or province boundary, and plot distributions of imperiled fishes by ecoregions or political boundaries. Data file last updated 4/25/2013.
The 2007 AFS Endangered Species Committee list of common and imperiled freshwater crayfishes of the United States and Canada
At this website, one can view lists of crayfishes by freshwater ecoregion, by state or province boundary, and plot distributions of crayfishes by ecoregions or political boundaries. Data file last updated 3/17/2011.
Information on benthic macroinvertebrate populations is currently available from numerous agencies in disparate databases. To maximize the value of these data, San Francisco State University and the U. S. Geological Survey have combined data from several of these sources into a single comprehensive database. To request this database, please contact Dr. Susan De La Cruz (email@example.com)
USGS personnel constructed, calibrated, and tested a model of flow and water temperature in the North Santiam and Santiam Rivers, Oregon. These rivers are major tributaries to the Willamette River, and have been listed as impaired by the Oregon Department of Environmental Quality (ODEQ) due to water temperatures that exceed the Oregon State water-quality standard.
As part of the U.S. Geological Survey's support of the technical analyses and temperature model development for Willamette Basin streams, U.S. Geological Survey (USGS) personnel carried out four dye studies in Willamette Basin streams in 2002.
Measurements of the surface width of the Willamette River's largest tributaries were included in this project in order to provide an important check on the water-temperature models being constructed as the foundation for the Willamette temperature Total Maximum Daily Loads (TMDLs).
