The dataset is composed of three data tables containing information from electrofishing and pebble count surveys conducted in tributaries to the Mohawk River in central and eastern New York during 2019 and 2023. 20 sites were surveyed in 2019, and 19 of those same sites were resurveyed in 2023. The 'Schoharie Creek below Bridge at Burtonsville NY' site was not resurveyed in 2023 because persistently elevated flows and turbidity at that location prohibited sampling. The first table contains information on the sampled reaches, the second table contains fish collection data, and the third table contains pebble count data.

The dataset is composed of two data tables containing information from boat electrofishing surveys conducted during 2021, 2023, and 2024 in sections of the Mohawk River where it runs separately from the New York State Canal System (i.e., is not canalized). The first table contains fish collection data and the second table contains information on the sampled reaches.

The dataset is composed of two data tables containing information from boat electrofishing surveys of two tributaries to Lake Ontario, Eighteenmile Creek and Oak Orchard Creek during June 2019. The first data table contains fish collection information and the second data table contains information on the sampled reaches.

Community composition data from multi-pass electrofishing surveys for assessing fish populations in headwater streams of the Adirondack Mountains, New York, USA. Each row represents one individual fish. This spreadsheet contains 11 columns. The first 7 columns describe the data (year collected, local site ID, stream name, latitude, longitude, USGS site number, and electrofishing pass number) and the remaining 4 columns describe each individual fish (common name, scientific name, total length (mm) and weight (g)). These data support the following publication: Baldigo, B.P., Sporn, L.A., George, S.D., and Ball, Jacob, in press. Efficacy of environmental DNA to detect and quantify Brook Trout Salvelinus fontinalis, populations in streams of the Adirondack Mountains, New York. Trans. Amer. Fish. Soc. na, na; http://dx.doi.org/10.1577/.

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.

The dataset is composed of four tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) at 12 sites on the Eastern Erie Canal in New York between Oneida Lake and the Hudson River from 2016 to 2023. The sampling techniques and frequency of sampling were adapted over time to optimize the efficiency of the study effort. From 2016-2019 eDNA water sampling and traditional fish surveys using seining, trapping, and benthic trawling were conducted twice annually (spring and summer) at the 12 sites. From 2020-2022, eDNA water sampling and traditional fish surveys using benthic trawling and electrofishing were conducted twice annually (spring and summer). In 2023, benthic trawling and electrofishing were conducted once (summer). The 12 study sites were selected to be approximately equidistant apart (~ 20 km) while also taking advantage of suitable access points. Within a study site, the exact areas that were sampled were often staggered by 500 m or occasionally more in order to find appropriate habitat for each gear type (i.e., wadable habitat for seining and habitat free of snags for trawling). The first table "eDNAData" contains environmental DNA data, the second table "FishCaptureData" contains fish community data from the traditional fish sampling methods, the third table "GobyLWData" contains length and weight measurements for all captured Round Goby beginning in 2020, and the fourth table "SiteData" contains information on the 12 study sites.

The dataset is composed of two data tables containing information from electrofishing surveys conducted in the Catskill and Adirondack regions. The first data table contains fish collection information and the second data table contains information on the sampled reaches.
