Background The invasive diatom Didymosphenia geminata (didymo) has historically been a wide-spread, but rare, micro algae found in moderately flowing cold-water streams of North America, Europe, Asia, and (more recently) New Zealand. Demographic patterns of didymo have recently changed resulting in greater spatial coverage and temporal persistence (e.g. blooms) in streams worldwide. Didymo blooms can form dense “woven fabric” aggregate up to 20 cm think, that trap algae, macroinvertebrates, detritus and other debris. The recent discovery of didymo in parts of New York State, including the Upper Esopus Creek in 2009, is concerning because blooms can affect benthic habitat, river hydraulics, the structure and function...

Problem Tribal Lands of the Shinnecock Nation Tribal community were inundated during Hurricane Sandy’s storm tide, resulting in detrimental effects on the Tribal Land’s natural resources. The existing science being used to inform decisions on remediation is biased toward activities are necessarily focused on the immediate aftermath of storms An assessment of the sources of contaminants that may have been introduced from inundation is needed to provide a context with which the Tribal community can better understand how to prioritize and manage the sources and minimize risk. Objectives This project will evaluate key human- and ecological-health concerns related to transport and persistence of...

Problem - Acidic precipitation has affected forested and aquatic ecosystems in New York, particularly in the Adirondack and Catskill regions. Acidification of surface waters and deleterious effects on fish and other biota have been well documented in both these regions. Despite reduced levels of acidity in atmospheric deposition over the past 20 years across New York and the northeastern United States, the most acid-sensitive streams and lakes have not yet begun to recover, and many show continued declines in acid-neutralizing capacity, an indicator acid-base status. Many studies have documented the effects of acid precipitation in New York, but thus far, there has been no comprehensive effort to synthesize and...
The U.S. Geological Survey (USGS) is collaborating with the New York Department of State (NYDOS) Office of Planning and Development to prepare a new Long Island South Shore Estuary Reserve (SSER) Coordinated Water Resources Monitoring Strategy (CWRMS). Since 2000, when the last CWRMS was published, numerous research projects and studies are demonstrating several new threats to the ecologic health and resilience of the SSER. Contemporary threats include: Eutrophic conditions brought on by high levels of nutrients from sewage treatment plant discharges, stormwater runoff, groundwater seepage, and atmospheric contributions; Increased occurrences of harmful algal blooms in the past 15 years; and, Growing concern...
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...

The Ellison Park wetland, a 423-acre, predominantly cattail marsh at the mouth of Irondequoit Creek in Monroe County near Rochester, N.Y., was evaluated for its potential role to decrease phosphorus loads that are derived from a 151-square-mile largely urbanized area and that ultimately enter and exacerbate efforts to ameliorate the eutrophic conditions in Irondequoit Bay. Monroe County's water-quality management plan included (1) modification of flow patterns upstream from and within the wetland by diverting storm runoff into backwater areas of the wetland, and (2) construction of a flow-control structure midway through the wetland that would cause short-term rises in water levels and increased dispersion of...

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...
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...
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,...

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...

A. BACKGROUND Aquatic macroinvertebrates, such as dragonfly larvae or crayfish have great potential for Mercury (Hg) monitoring, both as indicator organisms (or "sentinels'), and to provide critical information on Hg in lower food webs to assist in interpreting fish Hg levels. Despite these advantages, macroinvertebrates are not widely used in Hg monitoring because of the current need to directly analyze macoinvertebrate tissue for methyl-mercury (MeHg), at much greater expense than analyzing for total Hg (THg) (i.e. as a surrogate for MeHg), as with fish tissue. This is because the ratio of MeHg to THg in macroinvertebrates exhibits large taxonomic, spatial, and temporal variation, and there is no clear...

The distribution of mercury (Hg) and sites of greatest Hg methylation are poorly understood in Catskill Mountain watersheds. Although concentrations of Hg in the water column are low, high concentrations of Hg in smallmouth bass and walleye have led to consumption advisories in most large New York City reservoirs in the Catskill Mountains. Mercury in natural waters can exist in many forms, including gaseous elemental mercury (Hg0), dissolved and particulate inorganic forms (Hg(II)), and dissolved and particulate methylmercury (MeHg). Most Hg in living organisms is MeHg, a highly neurotoxic form that bioaccumulates in aquatic food webs. The production of MeHg by methylation of inorganic Hg in the environment...
The Catskill Mountains of southeastern New York receive among the highest loads of acid deposition in New York and the northeastern U.S. Additionally, the Catskills are underlain by sandstone and conglomerate, which is base poor and weathers slowly. Thus, the Catskills contain numerous streams with low (< 50 µeq/L) acid-neutralizing capacity (ANC) and are sensitive to impacts from atmospheric acid deposition. Since at least 1983, however, the levels of acidity in atmospheric deposition (primarily sulfuric acid) have been declining in the Catskills and throughout New York. While widespread recovery of streams in the Catskills has not yet been confirmed, recent data suggest that recovery in waters with ANC values...
