From 2013 to 2015, bathymetric surveys of New York City’s six West of Hudson reservoirs (Ashokan, Cannonsville, Neversink, Pepacton, Rondout, and Schoharie) were performed to provide updated capacity tables and bathymetric maps. Depths were surveyed with a single-beam echo sounder and real-time kinematic global positioning system (RTK-GPS) along planned transects at predetermined intervals for each reservoir. A separate set of echo sounder data was collected along transects at oblique angles to the main transects for accuracy assessment. Field survey data was combined with water-surface elevations in a geographic information system to create three-dimensional surfaces representing reservoir-bed elevations in the...
Background and Problem Prattsville has experienced severe flooding along the Schoharie Creek, most notably during August 2011 following Hurricane Irene, which severely damaged or destroyed large areas of the town, and caused several million dollars in damages (Figure 1). Before and during a flood, forewarning and emergency response are critical. The rescue efforts of emergency responders are often hampered by lack of an understanding of where flooding is occurring at any given moment, but also where flooding is likely to occur in the near future. Emergency responders would benefit from a library of flood-inundation maps that are referenced to the stages recorded at the U.S. Geological Survey (USGS) streamgage in...

Digital flood-inundation maps for a 2.9-square-mile area of Ithaca, New York, were created in 2015–18 by the U.S. Geological Survey in cooperation with the City of Ithaca, New York, and the New York State Department of State. The flood-inundation maps depict estimates of the maximum areal extent and depth of flooding corresponding to selected flood frequencies for Cayuga Inlet, Sixmile Creek, Cascadilla Creek, and Fall Creek and selected water-surface elevations of Cayuga Lake. Flood profiles for the stream reaches were computed by combining a one-dimensional step-backwater model for the stream channels and a two-dimensional model for the overbank areas. The resulting hydraulic model was calibrated by using water-surface...

Transects of near-surface continuous water-quality data and vertical profiles of the same parameters were collected over a 24-hour period from September 7 to September 8, 2023 in the Arthur Kill. The Arthur Kill is a tidal strait located between Staten Island, New York, and Union and Middlesex Counties, New Jersey, and connects Newark Bay to the north and Raritan Bay to the south. It is a major shipping channel for the Port of New York and New Jersey surrounded by industrial and highly developed land. Transects were collected using a Yellow Springs Instruments (YSI) EXO2 series water-quality sonde with a 5-second data collection interval while the boat was in motion. Vertical profiles of water-quality parameters...

This data release contains phytoplankton data and vertical profile measurements of water quality and light in oligotrophic (low nutrient) lakes within the Adirondack Park, New York State. Data were collected between June and October 2021 at five lakes. Four lake locations (Nearshore, Open Water, Layer, Bloom) were sampled representing one of four sample types (Bottom Sediment, Surface Water, Bloom Material, Layer). Water-quality field parameters (water temperature, dissolved-oxygen concentration and percent saturation, pH, specific conductance, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescent dissolved organic material) were measured at each sampling location from the surface to the...

On August 25, 2020, the U.S. Geological Survey conducted a bathymetry survey of a 550 meter long reach of the Black River near Great Bend, New York. The study reach began approximately 1,000 meters upstream from the State Route 26 bridge in Great Bend, New York. Depth data were collected primarily with a 1,200 kilohertz Teledyne RD Instruments RioPro acoustic Doppler current profiler (ADCP) with position data from differential global navigation satellite system (GNSS) Hemisphere V102 DGPS antenna (any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government). Water surface elevations were established using real-time kinematic (RTK) GNSS surveys;...

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...

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...
