U.S. Geological Survey streamgage matching results for water-quality sites of the Delaware River Basin

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-08-05T00:00:00Z
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 are filled). There are 5,008 unique water-quality sites and 19,396 records representing streamgage matches.
