Fishway Structure Data in the Eastern United States

These data are a compilation of fishway structures collected by the Atlantic States Marine Fisheries Commission state representatives at the request of the U.S. Geological Survey. The variables included within this dataset range from locality information and structure metadata (eg. latitude/longitude and year of construction) to metrics specifically about the fishway structure (eg. fishway width). The dataset ranges in dates of construction from 1882 to 2020 and includes fishways from all states on the eastern coast of the United States. Requests were sent to the Atlantic States Marine Fisheries Commission state representatives to collect fishway data from the areas within their responsibility. The state representatives...

Spatial Hydro-Ecological Decision System Summarized PRISM 30-year Normal Precipitation and Temperature Data for SHEDS Region 2

This data release is a summarization within the USGS Spatial Hydro-Ecological Decision System (SHEDS) framework of the Oregon State University PRISM Climate Group 30-year normal 800 meter resolution monthly, minimum and maximum temperature data and monthly precipitation data between 1991 and 2020. The output is a table consisting of the summarized values of these continuous variables for each local SHEDS catchment within the SHEDS Hydro-Region 2 along with a table of these variables individually processed through an upstream accumulation method for each catchment in SHEDS Region 2. This upstream accumulation method takes the local and upstream catchment values for a particular catchment, individually weighs them...

Data associated with the investigation of suitable habitat for the endangered plant Harperella (Ptilimnium nodosum Rose) in the Potomac River near Hancock Maryland

In lieu of a uniform mapping of the Chesapeake and Ohio Canal National Historical Park corridor at very high-resolution using UAS, this study developed a multi-scale workflow, where (1) geospatial modeling methods and (2) historic image analysis were used to constrain the areal extent of (3) detailed field and unmanned aerial systems (UAS) observation. Geospatial Modeling Methods: Harperella habitat characteristics reported by literature sources and corroborated by extremely limited harperella occurrence data (in the form of GPS locations), were compiled into a geospatial prediction model (GPM) to characterize the extent of harperella habitat for the region between Sideling Hill Wildlife Management Area and Harper’s...

Benthic macroinvertebrates abundance data for the study of urbanization effects in the Delaware Water Gap National Recreation Area, (2006)

This database contains aquatic benthic macroinvertebrate abundance data derived from samples collected from 33 75-meter stream site locations within the Delaware Water Gap National Recreation area in September of 2006. The database contains two separate table files (i.e., entities) in csv format: 1) Macroinvertebrate site abundance data and 2) site location data. For macroinvertebrate data, six samples were collected within 2-3 riffle areas within each site location with Portable Invertebrate Box Samplers (0.1-m2 sample area, 350 micron mesh collecting nets). Where possible, organisms were identified to the genus taxonomic level using a stereoscope except for organisms of the family Chironomidae and class Oliogochaeta,...

“ChesBay 24k – LU": Land Use/Land Cover Related Data Summaries for the Chesapeake Bay Watershed Within NHD Plus HR catchments

These tabular data are summaries of land use/land cover related variables within catchments of the Chesapeake Bay watershed using the Xstrm methodology at 1:24,000 scale. Variables being counted as land use/land cover related contain all land use and land cover data including datasets that are split off or combined from those data (eg. agriculture or impervious classes only datasets). Outputs consist of tabular comma-separated values files (CSVs) for both the local catchment and network summaries linked to the National Hydrography Dataset Plus High-Resolution (NHDPlus HR) framework by NHDPlus ID. Local catchments are defined as the single catchment the data is summarized within. Network accumulation summaries were...
