Surface Water Monitoring

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 i

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, Cross River,

PROBLEM As part of an effort to sustain a viable water-supply system for 8 million residents in New York City, and 1 million other residents in upstate New York that rely on City water, the New York City Department of Environmental Protection (NYCDEP) has requested a multi-disciplinary study by the U.S. Geological Survey (USGS) to determine the source(s) of water to surface-water sites (springs

• National Water Information System (NWIS): Find water-resources data collected at approximately 1.5 million sites, using menu-based and map-based front ends. • WaterWatch: View maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States.

Problem– Lake Ontario experienced period-of-record (1918-2017) maximum monthly average water levels during May through July 2017. NOAA lake gages recorded instantaneous peaks-of record, 249.2 at Olcott, 249.1 at Rochester, and 249.0 at Oswego and St. Vincent. These high water levels along with wind-generated waves caused flooding of thousands of residences and businesses and the erosion of miles o...

Tide stage, specific conductance, water temperature, and freshwater inflow at selected Hudson River (New York) gages updated every hour. Water temperature and specific conductance are measured at a depth of 10 feet below NGVD 1929 (mean sea level). These data include PROVISIONAL DATA subject to revision.This information has been made possible by funding from the U.S. Geological Survey Cooperative...

The U.S. Geological Survey New York Water Science Center’s monthly summary reports and tables of hydrologic conditions for surface and ground water list the station, county, period of record, and several statistics, including color-coded percent exceedance* categories based on average monthly conditions for the period of record at each station.

The New York Water Science Center conducts research and investigations used across a broad range of industries and other services.

U.S. Geological Survey Hydrologic Monitoring on Long Island, New YorkGroundwater is the sole source of water supply for more than 3 million people on Long Island, New York. Large-scale groundwater pumpage, installation of sanitary- and storm-sewer systems, and frequent variations in precipitation all have significant effects on regional groundwater levels and aquifer storage. In order to properly...

U.S. Geological Survey Hydrologic Monitoring on Long Island, New YorkMost streams and lakes on Long Island are hydraulically connected with the shallow groundwater system, and provide a window to the overall health of the underlying aquifer system. These water bodies are usually the first to show changes in the underlying aquifer, so there needs to be a consistent dataset of hydrologic data...

Flooding can be a serious problem in many parts of New York State. Information on floods and analyses of flood data are needed to aid in the design of bridges, culverts, dams, highways, and buildings, and for the prudent management of flood-prone areas. Documentation of floods and a more thorough understanding of flood hydrology and hydraulics will result in more effective management of flood...
