Adirondack and Catskill Stream-Fish Survey Dataset (ver. 7.0, December 2023)
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.

Environmental DNA and electrofishing data for American eel in the Mohawk and Hudson River Watersheds (ver. 2.0, January 2023)
The dataset is composed of five tables containing environmental DNA (eDNA) and electrofishing data from American eel (Anguilla rostrata) surveys conducted on parts of the Mohawk River watershed and tributaries to the Hudson River in New York. The dataset includes (a) eDNA data from 36 sites in the Mohawk River watershed and adjacent areas including parts of the Eastern Erie Canal, Mohawk River, an
Data from historic and contemporary fish community surveys in streams of the Adirondack Region
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 (2
Fish community and substrate data from tributaries to the Mohawk River (ver. 2.0, January 2024)
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. The first table contains information on the sampled reaches, the second table contains fish collection data, and the third table contains pebble count data.
Environmental DNA (eDNA) and fish capture data from Round Goby screening surveys on the Eastern Erie Canal, New York
The dataset is composed of two tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) on the Eastern Erie Canal in New York. Environmental DNA using water samples and traditional fish surveys using benthic trawling, seining, and trapping were conducted twice annually at 12 sites on the Eastern Erie Canal between Oneida Lake and the Hudson River f
Use of environmental DNA to assess American Eel distribution, abundance, and barriers in a river-canal system
Objective: The American Eel Anguilla rostrata historically was one of the most common fish species in Atlantic coast watersheds, but extensive dam construction and other factors caused a widespread population decline. One of the watersheds where American Eels have declined considerably is the Mohawk River in eastern and central New York. Recent attempts to characterize the distribution and abundan

Survey of fish communities in tributaries to the Mohawk River, New York, 2019
Fish communities of the Mohawk River and associated sections of the New York State Canal System have been well documented but little information is available regarding the status of fish communities in the extensive network of tributaries that feed the Mohawk River. This lack of information is problematic because changes in species distributions or general ecosystem health may go unnoticed in the

Condition of resident fish communities in the Eighteenmile Creek Area of Concern, New York
The lower 3.5 km of Eighteenmile Creek, a tributary to Lake Ontario in New York, was designated as an Area of Concern (AOC) in 1985 under the Great Lakes Water Quality Agreement due to extensive contamination of bed sediments by polychlorinated biphenyls (PCBs) and other toxicants. Five beneficial use impairments (BUIs) have been identified in this AOC, including degraded fish and wildlife populat

Survey of fish assemblages in the upper Neversink River and upper Rondout Creek, New York, 2017–19
Streams in the Catskill Mountains region of New York provide many important ecological and economic services, including recreational angling and serving as a drinking water supply to New York City. Many streams in this region were adversely affected by acid deposition during the late 20th century, impairing water quality and aquatic ecosystems. More recently, the level of acid deposition has decli

Eastward expansion of Round Goby in New York: Assessment of detection methods and current range
The Round Goby Neogobius melanostomus has spread rapidly around the Great Lakes region since its introduction to North America in 1990. In 2014, a specimen was captured in the New York State Canal System west of Utica, prompting concerns that Round Goby would soon reach the ecologically and economically valuable watersheds of Lake Champlain and the Hudson River estuary. The establishment of Round

Biological and chemical recovery of acidified Catskill Mountain streams in response to the Clean Air Act Amendments of 1990
Decades of acidic deposition have adversely affected aquatic and terrestrial ecosystems in acid-sensitive watersheds in parts of the eastern United States. The national Acid Rain Program (Title IV of the 1990 Clean Air Act Amendments - CAAA) helped reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) and resulted in sharp decreases in the acidity of atmospheric deposition.
