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.

During the recent droughts of 2007-2010 and 2012-2017, groundwater pumping has increased from the combined effects of the drought and land-use changes, re-initiating land subsidence. In order to document historical subsidence and monitor continued changes, the USGS has gathered and interpreted data from a variety of sources.

This map shows the location of stream gages where the water level is currently at or above flood stage (depicted as a black triangle) or at high flow (depicted as blue circles) The high flow conditions are expressed as percentiles that compare the current (i.e., within the past several hours) instantaneous flow value to historical daily mean flow values

The GLRI Edge-of-Field Monitoring project focuses on identifying and reducing agricultural sources of excess nutrients which can threaten the health of the Great Lakes. This geonarrative details the basics of edge-of-field monitoring (EOF), explores EOF applications, shows USGS is working collaboratively with our partners, and discusses how EOF can improve conservation efforts.
