Background The New York State Department of Environmental Conservation (NYSDEC) and Adirondack Lakes Survey Corporation (ALSC) repeatedly surveyed fish assemblages and characterized water chemistry from 44 to 52 lakes during the periods 1984-1987 and 1994-2005, and 2008-2012 to document the regional effects of acidic deposition and potential recovery associated with the 1990 Clean Air Act Amendment (CAAA) under the Adirondack Long-Term Monitoring (ATLM) Project. An initial analysis of changes in fish assemblages between the periods 1984-1987 and 1994-2005 noted modest and mixed recoveries, identified five fish-community response/recovery classes, and helped to devise a fish-community index based on species acid...
Background Forested watersheds in the southwestern Adirondack Mountains of New York received some of the most acidic deposition in North America from the 1970s through much of the 1990s (NADP 2005). Thus it is not surprising that associated effects on surface-water quality and ecosystems in lakes and streams of the southwestern Adirondack Mountains of New York were investigated to various extents over the past 35 years; first to document acidification effects and then to evaluate potential recovery. In fact, evidence of adverse impacts on water quality and aquatic ecosystems across the region provided much support for implementation of the Clean Air Act (CAA) of 1990. Although the underlying effect mechanisms were...

Fish mercury (Hg) data were compiled for 392 unique locations on freshwater streams and rivers in New York State for the period 1969-2016. A total of 7620 records were compiled from state, federal, and non-governmental organization databases. The compiled data were for samples of 65 non-anadromous species or species groups in which Hg was analyzed in whole fish or edible flesh, and for which sufficient ancillary data were available for interpretation. This data release provides total Hg concentrations on a wet weight basis, ancillary sample data (e.g., fish length, body part analyzed), collection location information (description, latitude, longitude), and source of original data. The data release also contains...

Background Although New York State has more than 70,000 miles of streams and rivers, little is known about the status, distribution, and trends of mercury (Hg) levels in stream fish, or the environmental drivers of these patterns. Streams and their riparian zones provide critical habitat for fish, birds, mammals, reptiles and amphibians, and serve as the interface between aquatic and terrestrial Hg transfer, transformations (most notably methylation) and bioaccumulation. Importantly, monitoring data from lakes (e.g., Simonin et al. 2006) does not transfer reliably to streams because of fundamental differences in Hg cycling and bioaccumulation processes. An assessment of fish Hg bioaccumulation focused on New...

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitoring the overall condition of the watershed, and by combining stream and soil monitoring within watersheds, the response of Adirondack ecosystems to environmental disturbances such as acid rain and climate change can be better understood. For example, the unexpectedly slow reversal of stream acidification from decreased atmospheric...
Background: Streams are ecologically, culturally, and economically important systems that are subject to impacts from a large array of human activities. There has been a relatively recent increase in efforts to manage, protect, and restore streams that have experienced physical, chemical, and biological degradation. Unfortunately, interest in any single restoration effort tends to be relatively short lived, and despite spending >$1 billion annually in the U.S. on stream restoration, little or no effort is devoted to evaluating the effectiveness or ecological success of most restoration projects (Bernhardt et al., 2005; Roni and Quimby, 2005). The limited post-restoration monitoring that occurs in many restoration...
Background: The waters of the Mohawk River basin are inhabited by one of the richest fish communities on the East Coast. The American Eel, Anguilla rostrata, is a unique member of this community, exhibiting a catadramous (maturing in fresh water and spawning in salt water) life history. Like many migratory fish, the American Eel has suffered a general decline across the East Coast largely attributed to barriers to migration and habitat degradation and other anthropogenic disturbances to the point that the species has been recommended for listing under the Endangered Species Act twice in the past ten years A recent study by Machut et al. (2007) and the implementation of a NYSDEC-initiated citizen science juvenile...

The lakes, rivers, and streams of New York State provide an essential water resource for the State. The information provided by time series hydrologic data is essential to understanding ways to promote healthy instream ecology and to strengthen the scientific basis for sound water management decision making in New York. The U.S. Geological Survey, in cooperation with The Nature Conservancy and the New York State Energy Research and Development Authority, has developed the New York Streamflow Estimation Tool to estimate a daily mean hydrograph for the period from October 1, 1960, to September 30, 2010, at ungaged locations across the State. The New York Streamflow Estimation Tool produces a complete estimated daily...

Problem The mainstem of the Mohawk River extends from Lake Delta Dam near Rome, NY downstream to its confluence with the Hudson River near Cohoes, NY. It supports a diverse fishery that is used extensively by recreational anglers. Smallmouth bass (Micropterus dolomieu) and walleye (Sander vitreus) are among the most popular game species with anglers but past biological surveys have documented at least 56 fish species that inhabit the river. An extensive fish survey of the Lower Mohawk River was last conducted by the New York State Department of Environmental Conservation (NYSDEC) from 1979-1983. Some key findings of this research include: • the river supported an abundant and fast growing smallmouth bass...

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 from 2016-2019. 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...
