Background: The waters of the Mohawk River and its tributaries are inhabited by some of the most diverse fish communities in the Northeast. The construction of the Erie Canal in 1825, and later the Barge Canal in 1918, enabled the westward expansion of fishes from the Hudson River drainage as well as the eastward expansion of fishes indigenous to the Great Lakes drainage. Today, almost half of the fish species in the Mohawk River are nonnative (Carlson and Daniels, 2004) and George et al (2016), yet the fish community still fulfills many important economic and ecological functions. The Round Goby (Neogobius melanostomus) is an invasive benthic fish indigenous to Ponto-Caspian region of Eurasia that is invading eastward...

Groundwater in the Newark basin aquifer flows primarily through discrete water-bearing zones parallel to the strike and dip of bedding, whereas flow perpendicular to the strike is restricted, thereby imparting anisotropy to the groundwater flow field. The finite-element model SUTRA was used to represent bedrock structure in the aquifer by spatially varying the orientation of the hydraulic conductivity tensor to reflect variations in the strike and dip of the bedding. Directions of maximum and medium hydraulic conductivity were oriented parallel to the bedding, and the direction of minimum hydraulic conductivity was oriented perpendicular to the bedding. Groundwater flow models were prepared to simulate local flow...

Problem - In August 2000, eleven sites were sampled from 9 streams within the Croton watershed for pharmaceuticals and other organic compounds associated with wastewater as part of a national study of these compounds in streams receiving wastewater discharges. Results from the national study indicated that streams in the Croton Reservoir downstream of sewage treatment plants had concentrations of target compounds. Detected compounds included pharmaceuticals, detergent degradates, insecticides, caffeine, and other organic compounds (Kolpin and others, 2002). The results indicate that these compounds are commonly present in streams below wastewater treatment plants (WWTPs). Many of these compounds have not been...

Problem The shallow groundwater of Nassau and Suffolk Counties is prone to contamination from current land-use, including agricultural, residential, and recreational. The aquifer system of Long Island is highly susceptible to human-derived contamination, in particular, because the soils and underlying sediments are generally composed of sandy, permeable materials that allow contaminants to move readily from the land surface into the groundwater below. Of increasing concern are the human-derived contaminants stemming from past and present uses of pesticides. In addition to the threat of direct runoff to adjacent waterbodies, pesticide transport through the shallow aquifer from inland sources may discharge to the...

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries...

BACKGROUND Long Island Sound has 600 miles of coastline and there are over 23 million people living within 50 miles of its shores. In response to water-quality issues and nitrogen pollution in the Sound, Congress created the Long Island Sound Study (LISS) in 1985. LISS is a partnership of federal, state, and local government agencies, private organizations and educational institutions working together to restore and protect the Sound. The USGS New England and New York Water Science Centers are partners in the LISS. These organizations also have historical and ongoing work with other partners in the LISS study region. Although historically the focus of LISS has been on water quality issues, a “Sustainable and Resilient...

Summary: This study aims to do a thorough analysis of trends in peak streamflows on Long Island. Reliable information about the magnitude and frequency of floods is essential for flood insurance studies, flood-plain management, and the design of transportation and water-conveyance infrastructure, such as roads, bridges, culverts, dams, and levees. Federal, State, regional, and local officials need peak flow information to effectively plan and manage land use and water resources, protect lives and property in flood-prone areas, and determine flood-insurance rates, particularly in densely populated urban areas. Long Island is a regional economic driver which has experienced public health and safety issues due to extreme...

Summary: Extreme flooding can threaten life and property in flood-prone areas, as well as cause damage to critical infrastructure along roadways and canals. The effective management of these areas, and appropriate design of structures along rivers and streams, relies on understanding the magnitude and frequency of floods at gaged locations, and the ability to estimate these data at ungaged streams. Peak flow analysis and development of regional regression equations to estimate peak flow frequency and magnitude for New York have not been updated using any new data collected since 1999 (Lumia, 2006). As more data and newer technology have become available there is a need to update these data. The updated regression...

Problem - Plastic debris pollution in freshwater ecosystems is becoming a major ecosystem and public health concern. Plastic pollution is now identified as the most abundant anthropogenic debris and it is found throughout all marine environments, comprising 60-80% of all floating debris (Eriksen et al., 2013). This debris can have a lasting effect on marine life through ingestion or entanglement (Laist, 1987). Recent studies in small tributaries and freshwater environments (Baldwin, 2016) indicate microplastic pollution is pervasive across all hydrologic environments.

Background Heavy metals, phosphorus, and organic contaminants in water and sediments of the lower Genesee River, resulted in the designation of fourteen beneficial uses as impaired in the Rochester Embayment Area of Concern (AOC). The benthic macroinvertebrate community or “benthos” Beneficial Use Impairment (BUI) was designated as degraded in the Genesee River because the New York State Department of Environmental Conservation (NYSDEC) impairment metrics generally identified slight to moderate impacts through the 1990s and 2000s. Accumulation of “sediments on more suitable substrates” and “contaminants in sediment of the Genesee River related to past municipal and industrial waste-water treatment plant discharges...

Problem Sediment transport is a serious concern in the upper Esopus Creek watershed. The creek is a well-documented source of sediment and turbidity to the Ashokan Reservoir, which is part of the New York City water supply system. During the last 2 decades there has been a series of stream stabilization and sediment reduction projects completed in the upper Esopus Creek watershed intended to reduce the suspended sediment load and turbidity levels delivered to the reservoir. During the last 7 years there has been a concerted effort to measure the effect of these projects on turbidity and suspended sediment. There is currently a large, long-term turbidity and suspended sediment study underway within the upper Esopus...

Introduction Ongoing efforts to improve the health of New York's South Shore Estuary Reserve (SSER) require continuously recorded water-quality data to understand the short-term effects of stormwater runoff and other pollution sources. To document the diel and tidal variability of water quality in the western bays of the SSER, the USGS monitors select physical and chemical parameters at two sites within the SSER. One site, station 01310740 on Reynolds Channel at Point Lookout, is near the estuary mouth and operated in cooperation with the New York State Department of Environmental Conservation (NYSDEC) and Town of Hempstead Department of Conservation & Waterways. The second, station 01311143...

INTRODUCTION Naturally occurring methane has been noted at some locations in the upper Devonian shale bedrock and in overlying glacial deposits in parts of Broome, Tioga, and Chemung Counties in south-central New York State (Williams, 2010). Systematic sampling of water wells for dissolved methane is needed to determine if the topographic and hydrogeologic setting of a well is related to methane occurrence. Objective and Study Area - The objective of this study is to characterize the natural occurrence of dissolved methane gas in groundwater from water wells within four different topographic and hydrogeologic settings (upland and major valley areas where bedrock is confined or unconfined by glacial deposits)....

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...

Water-quality samples were collected from the Upper Delaware Scenic and Recreational River (UPDE) and its tributaries during the period October 1, 2005, to September 30, 2007, to document existing water quality, determine relations between land use and water quality, and identify areas of water-quality concern. A tiered water-quality monitoring framework was used, with the tiers consisting of intensively sampled sites, gradient sites representing the range of land uses present in the basin, and regional stream-survey sites. Median nitrate and total phosphorous concentrations were 1.15 and 0.01 milligrams per liter (mg/L) for three sites on the mainstem Delaware River, 1.27 and 0.009 mg/L for the East Branch Delaware...

The current information available for the Genesee River and watershed is insufficient to assess if the Beneficial Use Impairment (BUI) delisting criteria for the Rochester Embayment Area of Concern (AOC) can or have been met. With on-going and future projects that are implementing best practices to control soil erosion and the reduction of nutrients that reach the Rochester Embayment, the river and the watershed, it becomes a necessity to: 1.) collect more frequent Total Suspended Sediment (TSS) data for the Genesee River both within and outside of the AOC; and 2.) to have a study design capable of evaluating the impact/success of the current and proposed GLRI projects in the watershed. This project is envisioned...
