New York Nowcast predicts water quality conditions at select beach swimming areas in NY. The Nowcast estimates conditions by merging environment and climate data with variables measured at a beach by 8 AM each morning and entering them into a computer program which provides a probability from 1 to 100 as to whether or not the beach has exceeded the bathing-water standard of 235 units of E. coli.

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.
A Python package to pre-process and hydro-enforce digital elevation models using hydrography features for use in the U.S. Geological Survey (USGS) StreamStats project.
