- The US Geological Survey (USGS) maintains stream-gaging stations in Massachusetts. This statewide datalayer, GAGES94_PT, represents the stations managed by USGS in 1994. Though maintained by USGS, these seventy one stations are funded by various sources. The points in this datalayer are fairly stable from year to year, though new gages are added and others removed as project work requires.
