The University of Wyoming Stream Species Dataset is a species presence dataset containing presence locations for 116 freshwater fish species in Wyoming, Montana, and the surrounding states. It contains data from 40,490 unique sample events (location, month, year). Data was derived from multiple sources (Table 1) and limited to fish occurrences in rivers and streams.

This USGS data release documents presence and absences of 419 fish species in the conterminous United States for 35,918 stream reaches of the National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1). Sample dates for this dataset span 1990-2019. Fish samples were aligned to the Integrated Taxonomic Information System (ITIS), where each species record was assigned a Taxonomic Serial Number (TSN). The dataset is structured with records representing a stream reach (i.e. comid), sample description (i.e. source, date) and a series of 419 columns representing species where each species column is named as the TSN. Data can be visualized on the NHDPlusV2.1 after a tabular join using the field 'comid' or can be projected and visualized as point data using the latitude and longitude fields (using coordinate reference system NAD83) that represent the midpoint of the stream reach that they were associated with. Data are provided in comma separated value (CSV) format.

The dataset includes measurements of stream habitat, fish abundance of westslope cutthroat trout and bull trout, and species-specific measures of environmental DNA (eDNA) from within the water. The data covers multiple streams in western Montana.

Stream habitat characteristics, energy development metrics, and fish catch per unit effort data for 91 sites (100m stream reach) sampled in the summers of 2012 and 2013.We sampled four streams in the Dry Piney Drainage (Dry Piney, Beaver Dam, Black Canyon, and North Black Canyon), five in the Fogarty Drainage (North and South Fogarty, North and South Pine Grove, and Sawmill) and four in the South Beaver Drainage (North Beaver, South Beaver, Middle Beaver, and Spring).

These data include 2015 - 2018 eDNA field sample points indicating lab results for presence or absence of bull trout. Sample sites are spaced at a 1 kilometer interval throughout the historical range of bull trout. eDNA stream samples are collected and species presence/absence is determined by analyses at the National Genomics Center. Results are recorded in the feature attribute table of the eDNA sample site shapefile. One point feature in the shapefile was generated for each 1 kilometer sample point in the bull trout eDNA feature class. Where multiple samples were collected at a single eDNA sample site, replicate point features will occur at a single location in the shapefile. The bull trout is an ESA-listed species with a historical range that encompasses many waters across the Northwest. Though once abundant, bull trout have declined in many locations and are at risk from a changing climate, nonnative species, and habitat degradation. Informed conservation planning relies on sound and precise information about the distribution of bull trout in thousands of streams, but gathering this information is a daunting and expensive task. To overcome this problem, we coupled 1) predictions from the range-wide, spatially precise Climate Shield model on the location of natal habitats of bull trout with 2) a sampling template for every 8-digit hydrologic unit in the historical range of bull trout, based on the probability of detecting bull trout presence using environmental DNA (eDNA) sampling (McKelvey et al. 2016). The template consists of a master set of geospatially referenced sampling locations at 1-kilometer intervals within each cold-water habitat. We also identified sampling locations at this same interval based on the U.S. Fish and Wildlife Service's (USFWS) designation of critical spawning and rearing habitat. Based on field tests of eDNA detection probabilities conducted by the National Genomics Center for Wildlife and Fish Conservation, this sampling approach will reliably determine the presence of populations of bull trout, as well as provide insights on non-spawning habitats used by adult and subadult fish. The completed bull trout eDNA survey results are available through an interactive ArcGIS Online Map. The map provides the ability to zoom in and look at an area of interest, as well as to create queries or select an area to download points as a shapefile.

This Data Release compiles records of brook trout abundance from 745 unique sites across the southern Appalachian mountains from 1958-2021. Records were compiled from 10 institutions, primarily state natural resource agencies. Data were collected from wadeable stream environments with standard backpack electrofishing methods, and observed abundances of adult and juvenile brook trout are reported for each electrofishing pass within sample sites.
