Background 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 drainage area of Upper Esopus Creek, between the source (Winisook Lake) and the Ashokan Reservoir is approximately 192 mi2. The Schoharie Reservoir, located 27 miles north of the Ashokan Reservoir, also supplies water to Upper Esopus Creek (and to the Ashokan Reservoir) 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...

Problem The presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...

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...

Description of Study The objective of this study was to define specific conductance in stream water under low streamflow conditions in Central New York. The study area covers parts of six counties in the Southern Tier region of New York State (fig. 1). This survey covered a range of watershed areas and land use types, and specifically targeted low-flow periods during the summer as the flow would be mostly derived from groundwater discharge at this time and represents the upper limit of conductance that can currently be expected. This study was funded by the New York State Department of Environmental Conservation. Methods The network of sites sampled was created using ARCMAP software. Over 280 sites were selected...
