Summary
This data set contains U.S. Geological Survey (USGS) streamgage matching results in tabular format for water-quality sites retrieved from the Water Quality Portal for the Delaware River Basin. The table contains a list of water-quality sites joined to USGS streamgages where the water-quality site and USGS streamgage are located on the same stream, as represented by the National Hydrography Dataset Plus (NHDPlus) "LevelPathID" attribute. The file represents a one-to-many relationship: each water-quality site, as represented by the unique identifier, "MonitoringLocationIdentifier", is joined to anywhere from zero streamgages (not on same stream as any gage; the gage info columns are NA) to one or more streamgages (the gage info columns [...]

There are 5,008 unique water-quality sites and 19,396 records representing streamgage matches.

The purpose of the streamgage matching process was to identify which USGS streamgage or streamgages are on the same stream as a water-quality site. USGS streamgages measure stream and river flow, which is essential to understanding how water quality varies and changes over time. This table provides information about the proximity and relative location of the water-quality site to the streamgage, and some additional fields that might be useful in the preliminary screening of matches, like if the streamgage has daily mean discharge data and has been recently active.
