Surface-water quality in the Lake Erie/Niagara River Basin of New York State
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...
Bathymetry of New York City’s East of Hudson Reservoirs
Background: The New York City Department of Environmental Protection (DEP) maintains an extensive network of reservoirs and aqueducts for water collection, storage, and transport; it supplies more than one billion gallons of drinking water daily to more than nine million people. The East of Hudson (EOH) network (fig. 1) includes thirteen reservoirs – Amawalk, Bog Brook, Boyd Corners...
Flood-Inundation Mapping for Schoharie Creek at North Blenheim, NY
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...
Ambient Groundwater Quality Monitoring in New York
Over one-third of New York State (NYS) residents rely on groundwater as a potable drinking water source. Understanding the quality of NYS groundwater is important for the protection of public health and security of this resource.
Mohawk River Basin Water Quality
Elevated levels of nutrients (for example, phosphorus) in the Mohawk River can lead to eutrophication and potentially toxic blue-green algal blooms. The U.S. Geological Survey (USGS), in cooperation with the New York Department of Environmental Conservation (NYSDEC) collected nutrient samples and measured streamflow in the Mohawk River. These data are being used to develop a water-quality model...

Surface-water Quality in the Mohawk River Basin (Pilot RIBS/TMDL)
Problem The quality of surface water has important effects on human and ecological health. Surface water is an important drinking water source and is used for swimming, fishing, and recreation, and the quality of surface water can have profound effects on the health, diversity, and resilience of ecological communities. The New York State Department of Environmental Conservation (NYSDEC)...
Flood-Inundation Maps for Four Stream Reaches, Ithaca, Tompkins County, New York
Problem The City of Ithaca, Tompkins County, N.Y., is in the process of developing a flood management plan for the streams that flow through the City. Flooding in the City is an annual problem caused by a variety of distinct and sometimes interconnected reasons. Flooding often is a result of snowmelt and rain during the winter and spring. Slow ice-melt and breakup can lead to ice jams...
Bathymetry of New York City's West of Hudson Reservoirs
Background Every day, the New York City Department of Environmental Protection (DEP) supplies more than one billion gallons of drinking water to more than nine million people. To do this, the DEP maintains an extensive network of reservoirs and aqueducts. A major part of this system, the West of Hudson (WOH) network, in the Delaware and Hudson River drainages, includes six reservoirs...
Ambient Groundwater Quality Monitoring in New York
Introduction Relatively little data describing the quality of groundwater in New York State exists, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the Ambient Groundwater Quality Monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate...
