Barry Baldigo Scott George Dylan Winterhalter 20210902 Two data tables in both an Excel spreadsheet and in .csv text files. Reston, VA U.S. Geological Survey https://doi.org/10.5066/P9IP0AWU The dataset is composed of two data tables containing information from electrofishing surveys conducted in streams of the Adirondack region. The first data table contains information on the sampled reaches and the second data table contains fish collection information. Historical data (1979-1999) were collected by the New York State Department of Environmental Conservation and contemporary data (2020) were collected by the U.S. Geological Survey. Streams were surveyed in 2020 to replicate historical surveys conducted by the New York State Department of Environmental Conservation (mainly in 1979 and 1999). Together, these three discrete snapshots in time (each separated by approximately 20 years) can be used to evaluate changes in stream fish assemblages following reductions in acid deposition resulting from the Clean Air Act Amendments in 1990 and other regulations. 19790911 20200811 ground condition Complete None planned -75.6 -73.4 44.3 43.1 Adirondack Mountain region of New York State USGS Thesaurus inland fishery resources fish population and community ecology freshwater ecosystems USGS Metadata Identifier USGS:60670bebd34edc0435c09b05 Geographic Names Information System (GNIS) Adirondack State Park Adirondack Mountains New York none none Barry Baldigo U.S. Geological Survey Research Biologist mailing and physical

Historic surveys conducted between 1979 and 1999 only used a single electrofishing pass through the the study reach while contemporary (2020) surveys used multi-pass depletion electrofishing surveys and typically conducted three consecutive electrofishing passes of the study reach.

Stream Name Name of stream/river from which fish were collected Producer defined Name of stream/river from which fish were collected USGS Station Number A unique site identification number from the National Water Information System (NWIS) near or at fish sampling site Producer defined 8-15 digit identifier Pass Number Electrofishing pass number Producer defined 1 3 Common Name Common name of fish species American Fisheries Society Blank indicates no fish captured in the pass Scientific Name Scientific name of fish species American Fisheries Society Blank indicates no fish captured in the pass Fish Length (mm) Total fish length in millimeters. A blank cell indicates that no fish were captured in the given pass. NA indicates that length was not measured. Producer defined 14 263 millimeters (mm) Fish Weight (g) Fish weight in grams. A blank cell indicates that no fish were captured in the given pass. NA indicates that weight was not measured. Producer defined 0.1 243.0 grams (g) "P" if Pooled "P" indicates length and weight were derived from batches of similarly sized individuals of the same species Producer defined P indicates length and weight were taken from a batch of similarly sized individuals of the same species. Length was taken from one representative individual from the batch and weight was determined by dividing the batch weight by the number of individuals. Blank cell indicates length and weight were taken from an individual fish. ScienceBase U.S. Geological Survey mailing and physical
