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...

The coastal areas of southeastern New York (fig. 1) are highly vulnerable to tidal flooding (fig. 2). Timely evacuation of people from flood-threatened areas in advance of approaching hurricanes and nor'easters (northeast coastal storms) requires adequate flood-warning time. To begin addressing this need for immediate information on coastal flooding, the U.S. Geological Survey (USGS), in cooperation with the Town of Hempstead Department of Conservation & Waterways, Village of Freeport, and New York State Department of Environmental Conservation, has operated a network of real-time tidal water-elevation and meteorological stations since 1997 in the coastal areas of Long Island and New York City. Each tidal water-elevation...

The St. Lawrence River at Massena Remedial Action Plan (RAP) Area of Concern (AOC) begins above the power dam facilities and seaway locks at the Massena Village drinking water intake and follows the river downstream for about fifteen miles to the international border. For New York State, the AOC includes portions of the Grasse, Raquette and St. Regis Rivers. There are three governmental agency groupings that share jurisdictional responsibilities for the AOC. These are the United States, Canada, and the St. Regis Mohawk Tribe at Akwesasne. The Cornwall portion of the AOC includes lands in Ontario, Quebec, and the Mohawks extending downstream of the power dam to the eastern outlet of Lake St. Francis. Since 2010,...

Problem Coastal communities are susceptible to damage from coastal storms and associated storm surge, and although tidal wetlands provide a buffer against shoreline erosion and aid in shoreline stabilization, they too are vulnerable to the action of storms. Tidal wetland dynamics need to be better understood, as they are also intrinsically valuable as nursery, feeding, and refuge areas for many commercial and recreational fisheries, and significantly contribute to the base of the marine food web. Wetlands trap sediments, reduce turbidity, and absorb nutrients and pollutants thereby improving water quality, and they provide many recreational opportunities. Tidal wetland stability needs to be assessed using a sediment...

Delhi has experienced severe flooding along the West Branch Delaware River (fig. 1); most notably during January, 1996, June, 2006, and October, 2010, and August, 2011. Emergency responders would benefit from a library of flood-inundation maps that are referenced to the stages recorded at the USGS streamgage upstream from Delhi. By referring to the appropriate map, emergency responders could discern the severity of flooding (depth of water and aerial extent), identify roads that are or will soon be flooded, and make plans for notification or evacuation of residents in harm’s way based on current and near-future flood levels. Digital flood-inundation maps for a 5 mile reach of the West Branch Delaware River through...

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 and Problem Flooding is a ubiquitous problem throughout New York State. The Schoharie Creek has experienced severe floods, including the devastating floods of August 2011 following Hurricane Irene, which severely damaged or destroyed many homes, businesses, roads, and other property within the Schoharie Valley. In North Blenheim, homes, the Blenheim Town Hall, fire hall, and maintenance hall were inundated; road were washed out and the historic covered bridge was destroyed. In addition to the flood of 2011, major floods occurred in April 1987, January 1996, and April 2005. Before and during a flood, forewarning and emergency response are critical to minimizing loss of life and property. The rescue efforts...

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 - There is a stated need to provide information on loading of persistent toxic pollutants to Lake Ontario from New York tributaries. The information is specifically required for the Lake Ontario Mass Balance Model, which is an integral part of the long-term Great Lakes research. The project described here is designed to demonstrate a cost-effective approach for estimation of loads of polychlorinated-biphenyls (PCBs) through use of a relatively small number of large-volume whole-water samples for PCB analysis. The Black River basin was selected to demonstrate the feasibility of the approach because it is the largest New York contributor of PCBs to Lake Ontario. Objectives - The objective of this project...
Hurricane Sandy has created three open breaches in the barrier island system along the south shore of Long Island, N.Y. In response, the National Park Service has sought assistance from the U.S. Geological Survey (USGS) New York Water Science Center (NYWSC) to help evaluate the open breach condition in Federal Wilderness near the Old Inlet area of Fire Island National Seashore, N.Y. The NYWSC evaluation is initially focusing on two activities: measurement of water velocities and depths within the Wilderness breach, and collection of water levels within Great South Bay (GSB) adjacent to the breach. Measurement of water velocities and depths within the Wilderness breach is being done with a Sontek 1 M9 acoustic...

Problem The Adirondack region of New York has 128 lakes that are listed as impaired by acidity under section 303(d) of the Clean Water Act. Acidity can limit the survival and reproduction of native fishes such as brook trout (Salvelinus fontinalis). Chronic and episodic acidification also stresses fish, aquatic macroinvertebrates, and other biota of inflowing tributaries of these and many additional lakes. Acidification of these tributaries can also affect the health of fish populations in receiving lakes, by limiting suitable spawning and nursery habitat. Although many Adirondack lakes have shown decreased acidity resulting from decreases in atmospheric sulfur and nitrogen emissions, the ecological improvements...
The United States Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), monitors a network of observation wells throughout New York to provide current information on the effect of climatic conditions on groundwater levels. At present (2015), there are 95 observation wells in unconsolidated and bedrock aquifers, all of which are equipped with telemetry for near real time data transmission. Daily groundwater levels and hydrographs for each well site are available online in the National Water Information System (NWIS). In addition, monthly assessments of ground-water conditions, based on frequency statistical analysis of the monitoring data, are provided...

INTRODUCTION • Concerns over the viability of the fractured bedrock aquifer that provides about 1/3 of Rockland County’s water supply prompted a 5-year study by the U.S. Geological Survey (USGS) to (1) define the hydrogeologic framework of the aquifer, (2) assess conditions within it, and (3) identify other potential sources of water for the County. The study was done in cooperation with Rockland County and the New York State Department of Environmental Conservation. • Population growth in Rockland County to nearly 300,000 people has been paralleled by significant hydrologic changes over the past 50 years –water demand and impervious surface area have increased, and sanitary sewers now serve most areas and discharge...

Problem The Village of Endicott relies on wells that supply ground water from sand and gravel aquifers within the Susquehanna River valley. Localized contamination in the Village of Endicott and elsewhere in the Susquehanna River Valley has been documented by U. S. Environmental Protection Agency (USEPA) and the New York State Department of Environmental Conservation (NYSDEC) from a number of commercial and industrial sites. Currently, the Village of Endicott treats its water prior to distribution and can purchase water from other nearby municipal sources as needed. The village would like to find an additional source of clean water to supplement The most viable clean source is likely to be in sand-and-gravel-filled...

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

Problem - Urbanization of the 150-square-mile Irondequoit Creek basin in Monroe and Ontario Counties, N.Y., continues to spread southward and eastward from the City of Rochester. Conversion of forested land to other uses over the past 40 years has increased to the extent that more than 50 percent of the basin is now developed. This expansion has increased flooding and impaired stream-water quality in the northern (downstream) half of the basin. A precipitation-runoff model of the Irondequoit Creek basin could be used as a management tool by water-resources managers to better understand the hydrology of the basin, permit simulation of planned or hypothetical land-use changes, evaluate the adverse effects of future...

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...

Problem The New York State Department of Environmental Conservation (NYSDEC) intends to develop a Nine-Element Watershed Plan (http://www.dec.ny.gov/chemical/103264.html) for the Lake Erie/Niagara Basin. To develop the Nine-Element Plan, NYSDEC needs a high quality, quality assured, nutrient-loading dataset to serve as a baseline against which future change can be measured and to identify areas in greatest need of water quality improvement. Objective and Scope The objective of this project is to collect baseline nutrient water-quality data that can be used to 1) build a watershed model that will help focus future water quality improvement efforts in the basin, and 2) aid in future regional target-setting efforts...
Problem Statement There are over 1.3 million residents in Nassau County that rely on groundwater as their sole source of potable drinking water. The mixed land uses (residential, commercial, industrial, agricultural, and recreational) of Nassau County contribute point and non-point sources of aquifer contamination. Nassau County water purveyors currently operate supply wells screened in the upper glacial, Magothy, and Lloyd aquifers. The protection and long-term sustainability of all three aquifers are vital concerns for the Nassau County Department of Public Works (NCDPW). Monitoring of groundwater for contaminants of emerging concern (CEC) associated with mixed land uses within these aquifers is necessary for...
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,...
