Problem The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern NY. Waters throughout upper reaches of both rivers currently range from neutral to severely acidic due to deposition of acid rain throughout their watersheds. Fish surveys conducted by the USGS during the late 1980s and early 1990s found that some fish species and entire assemblages were absent or depressed in many tributaries and second and third order reaches of both rivers. Recent decreases in acidity of atmospheric deposition and changes in hydrologic and thermal regimes are now affecting water chemistry (e.g., pH, acid neutralizing capacity, dissolved organic...

Background Fish communities of the mainstem Mohawk River and Barge Canal have been well-documented (Carlson, 2015; George et al., 2016) but comparatively less information is available regarding the current status of fish communities in tributaries to the Mohawk River. This information gap is problematic because long-term shifts in species distributions or abundances due to climate change, eutrophication, or other anthropogenic stressors may go unnoticed in the absence of baseline data. More importantly, an approaching invasive fish species, the Round Goby (Neogobius melanostomus), is expected to colonize much of the Mohawk River and the lower portion of many major tributaries. Introductions of Round Goby have had...

Background: The USGS propose a collaborative investigation with the NYSDEC and NOAA to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Niagara River Area of Concern (AOC). Using a probabilistic study design, sediment-toxicity data compiled by the USGS, invertebrate community data collected by NYSDEC, and sediment-chemistry data collected by NOAA will be assimilated using a Sediment Quality Triad approach (Chapman et al., 1992; USEPA, 1992) to provide a sediment-quality baseline needed to gauge changes expected to follow remediation of contaminated sediments in parts of the AOC. These data will also be used directly to confirm that the macroinvertebrate...

Background Discharges from non-point sources, municipal and industrial point sources, and combined sewage overflows over the last century resulted in elevated levels of heavy metals, conventional pollutants, phosphorus, and toxic organic contaminants in water and sediments of the Lower Genesee River and Rochester Embayment. As a result, the zooplankton and phytoplankton or “plankton” communities were designated as one of fourteen Beneficial Use Impairments (BUI); i.e., the resource was either impaired or in need of assessment in the Rochester Embayment Area of Concern (AOC). The Rochester Embayment Remedial Action Committee (RAC) was formed by the New York State Department of Environmental Conservation (NYSDEC)...
Problem - A variety of factors potentially impact natural resources in the Neversink River basin and in other tributaries to the Upper Delaware River along the New York, Pennsylvania, and New Jersey boarders in the northeastern US. Increased urbanization within most watersheds of the Delaware River has decreased forested lands and ground permeability; fractionated forests, streams, and rivers; impounded flowing waters, and discharged municipal, agricultural, and industrial pollutants into many waterways. The effects on water quality and hydrology have been quantified relatively well. The direct impacts of these perturbations on biological components of stream and river ecosystems are sometimes known, however, more...

Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal trends and potential recovery of fish assemblages in less acidic or less toxic streams. Though the effects of acidification on fish assemblages have been qualified in several streams of the eastern Adirondacks during 1979, the 1980s, and early 2000s, (Schofield and Driscoll 1987; Simonin et al. 2005) quantitative impacts were...

Background - Turbid waters originating in the Schoharie Reservoir allegedly impair habitat and resident trout populations in Upper Esopus Creek; however, to date no scientific studies have documented adverse affects of altered thermal, suspended sediment (turbidity), and flow regimes on survival, growth, or behavior of trout or the health of their populations. The 424 mi2 Esopus Creek watershed is a tributary to the Hudson River in the south-central Catskill Mountains of New York State and is often considered to be two systems separated by the Ashokan Reservoir. The Upper Esopus Creek is considered the reach between its source, Winisook Lake, and the reservoir. Flows in the Upper Esopus Creek are supplemented by...

Problem - The New York City Department of Environmental Protection (NYCDEP) Stream Management Program, in cooperation with local Soil and Water Conservation Districts, is implementing stream-restoration demonstration projects to decrease channel bed and bank erosion and improve water quality (lower suspended sediment and turbidity) in several priority streams of the Catskill Mountain Region (Fig. 1). A variety of issues relating to (a) the hydraulic geometry of stable and unstable stream channels, (b) validation of underlying assumptions used to characterize channel stability and design, and (c) the effects of restoration on stream-channel geomorphology, stability, biota, and sediment transport have not been...
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...

American Eel (Anguilla Rostrata) Background The U.S. Geological Survey (USGS) has worked in cooperation with The Nature Conservancy (TNC) over the past 11 years to study the effects of channel geomorphology and impoundments on the distribution of common and rare mussels in the Neversink River and to characterize fish assemblages in tributaries to the Upper Delaware River in New York, Pennsylvania, and New Jersey. The focus of this research and monitoring program has recently shifted toward studies of the rapidly declining American eel (Anguilla rostrata) populations in rivers of the tri-state region. There are many factors that could potentially cause the observed declines in local and continental populations of...
Project Summary. The Western Adirondack Stream Survey (WASS), conducted in 2003-2005, showed that acidic deposition was causing toxic forms of Al to move from soils to streams in 66% of the 565 watersheds assessed in the study region. The WASS encompassed only 20% of the Adirondack region, and for the remaining 80% (referred to hereafter as the East-Central Adirondack region), there is little information on the extent of soil and stream acidification. Based on lake-chemistry data, acidification in the East-Central Adirondack region has been considered minimal relative to the Western Adirondack region. However, some lake acidification has been identified, and WASS results showed that lake acidification under...
Problem Almost 1900 public, private, and commercial waste-water treatment plants (WWTPs), many located upstream of drinking water intakes or within tributaries to water-supply reservoirs, are permitted to release effluents into surface- or ground-waters across New York State. More than 150 facilities have New York State SPEDES permits to discharge waste waters in the New York City East of Hudson and West of Hudson Water Supply Watersheds (NYC Watersheds), which provide drinking water to more than nine million people in and around New York City. Some common waste water treatment plant (WWTP) contaminants (e.g., polycyclic musks, alkylphenols, and estradiol) can cause estrogenic or androgenic changes in the reproductive...
Problem - The Esopus Creek is located in the Catskill Mountains of New York State and is part of the New York City (NYC) drinking water supply system. The basin was dammed in 1915 to form the Ashokan Reservoir splitting the creek into Upper (upstream of the reservoir) and Lower segments. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, supplies water to Upper Esopus Creek via the Shandaken tunnel. Waters from the Schoharie watershed enter Upper Esopus Creek at the Shandaken portal and travel 18 km before entering the Ashokan Reservoir. The two reservoirs account for approximately 40% of NYC’s mean annual water supply. Waters from the portal have been the focus of controversy and legal action,...

Description of Work This study will generate bed sediment toxicity and benthic community data needed to test two related hypotheses that address the two criteria for delisting the benthos BUI. The first hypothesis is that bed sediments at selected sample locations in the AOC (in three tributaries and in the St. Lawrence River) are no more toxic to the test species than bed sediments collected from control sites located outside (generally upstream from) the AOC. Acute (survival) and chronic (growth) whole bed-sediment toxicity tests will be conducted using the midge (Chironomus dilutus), following standard methods (USEPA 1994; USEPA 2000). The second hypothesis is that the benthic macroinvertebrate communities from...

The New York State Department of Environmental Conservation (NYSDEC) is developing a unit management plan/environmental impact statement (UMP/EIS) for the Hudson Gorge Primitive Area, an area of Forest Preserve land encompassing a scenic stretch of the Hudson River in the Adirondack Park. Two goals of the UMP/EIS are to inventory natural resources and ecosystems and take actions to protect those resources while providing for appropriate types and levels of public recreational use. Because of the river's extensive whitewater reaches, it is the setting for a commercial rafting industry that operates during spring, summer, and fall. To increase flows in the Indian and Hudson Rivers, the Town of Indian Lake conducts...

Background: Rainbow Trout (Oncorhynchus mykiss) have thrived in the Esopus Creek since their introduction in the 1880s. The construction of the Ashokan Reservoir in 1915 changed the fishery by providing a stable lentic environment where adult trout could grow large and find refuge during periods when stream conditions become stressful. Although many adult Rainbow Trout spend time in the reservoir, it is believed that spawning occurs almost exclusively in the tributaries; most notably the Upper Esopus and its tributaries. Thus, the health of individual Rainbow Trout and the size of their spawning runs out of the Reservoir not only regulate the species’ future population in the reservoir, but also the population...
Problem - Geomorphologic techniques for stream channel and bank restoration are fast becoming the techniques of choice among federal, state, county, and local agencies to reduce suspended sediment loads, reduce flood damage, improve aquatic habitat, and generally stabilize stream channels. One reason for this upswing in use is that appropriate application of these techniques has been shown to reduce the need for repetitive visits to a reach to remove sediments or repair stream banks, and thus reduce long-term channel maintenance expenses. Geomorphologic restoration projects require data that define what a stable stream channel should look like in a given region. Regional hydrologic curves and regional channel-geomorphologic...
