Floodplain data from the Hoh, Elwha, Queets, and Quinault Rivers in Olympic National Park, 1939-2013

Floodplain margins, defined as the unvegetated portion of the active flow zone, were determined for four rivers in Olympic National Park, Washington, USA, from the 2013 National Agriculture Imagery Program (NAIP) orthophotomosaic. Transects were established orthogonal to the active river corridor (braids) across the width of the floodplain from point locations placed at 250 m intervals along...

Oregon spotted frog (Rana pretiosa) observations in Oregon, 2016-2018

This dataset contains information from surveys conducted 2016-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort in Oregon. USGS research activities in 2016, 2017, and 2018 were divided into six study design categories: breeding (egg mass counts), mid-level (visual encounter surveys for occupancy monitoring), apex (mark-recapture), telemetry, trapping, and...

RockType to Permeability Crosswalk Table, Northwest U.S.

This table is a crosswalk or lookup table that classifies rock type (surface geology) by its permeability, or the ability to pass substances, such as liquids or gases. The rock types that are classified are located in the Northwest U.S. -- Oregon, Washington, Idaho, Utah, Nevada, Wyoming, and Montana.

Probability of Streamflow Permanence (PROSPER) Model Output Layers, (ver. 2.0, February 2019)

The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual predictions...

Oregon Spotted Frog Monitoring at Jack Creek 2015-2018 (final)

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the time each survey...

Streamflow Permanence Class rasters (PROSPER), 2004-2016, (ver. 2.0, February 2019)

Streamflow Permanence Class (SPC) rasters represent the classification of the raw streamflow permanence probabilities produced by the PRObability of Streamflow PERmanence (PROSPER) model into categorical wet and dry classes, annually for years 2004 through 2016, and overall mean. Raw probabilities were classified into a -5 (dry) to +5 (wet) scale based on the spatially variable threshold (i.e...

Streamflow Permanence Probability rasters (PROSPER), 2004-2016, (ver. 2.0, February 2019)

Streamflow Permanence Probability (SPP) rasters represent the raw streamflow permanence probabilities produced by the PRObability of Streamflow PERmanence (PROSPER) model, annually for years 2004 through 2016, and overall mean and standard deviation. The PROSPER model is a GIS raster-based empirical model of probabilistic predictions of a stream channel having year-round flow for any...
