USGS is a primary source of geographic information system (GIS) data. Our data and information is presented in spatial and geographic formats, including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more.
Borehole geophysics is the science of recording and analyzing measurements of physical properties made in wells or test holes. Probes that measure different properties are lowered into the borehole to collect continuous or point data that is graphically displayed as a geophysical log.
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 National Water Information System (NWIS) provides access to data at over 1.5 million sites. There are 56 possible site types used in the NWIS data base, including 14 primary types and 42 secondary types. To simplify mapping of the site locations for most practical applications, the site types are displayed in 5 groups that include the following primary and secondary types.
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.
StreamStats for New York can be used to estimate (1) instantaneous flood discharges with exceedance probabilities of 0.8, 0.667, 0.5, 0.2, 0.1, 0.04, 0.02, 0.01, 0.005, and 0.002 (1.25-, 1.5-, 2-, 5-, 10-, 25-, 50-, 100-, and 500-year recurrence intervals, respectively) for ungaged, unregulated, rural streams throughout NY; (2) bankfull discharge and channel characteristics of streams in NY.
Available online are estimated Secchi-disk transparency (eSDT) and corresponding estimated trophic state index (eTSI) values for Michigan inland lakes. To view available eSDT for Michigan inland lakes greater than 20 acres without interference from clouds, cloud shadows, dense vegetation or shoreline, go to the Michigan Lake Water Clarity Interactive Map Viewer.
Hydrologic Conditions Network Map displays Streamflow Monitoring Network, Groundwater Bedrock Aquifer Monitoring Wells, and Groundwater Unconsolidated Aquifer Monitoring Wells in New York State Drought Regions.
