This data release child item provides streamflow statistics and basin characteristics (potential explanatory variables) for groundwater contributing areas of 4 USGS streamgages with 14 water years or more of record, 3 discontinued USGS streamgages with 1 to 3 water years of record, and 11 USGS partial-record stations with at least 10 or more miscellaneous measurements. These data were used to develop regional regression equations for the 99-, 98-, 95-, 90-, 85-, 80-, 75-, 70-, 60-, and 50-percent flow durations. Information on Maintenance of Variance Extension, type 1 (MOVE.1) record extension analyses for estimated streamflow statistics at the 3 discontinued streamgages and 11 partial-record stations are provided. The Weighted-Multiple-Linear Regression (WREG) input and output files used to develop the final regional regression equations for Massachusetts are also provided. \nThis child item also provides additional streamflow statistics for the: 40-, 30-, 25-, 20-, 15-, 10-, 5-, 2-, and 1-percent flow durations; monthly 90- and 50-percent flow durations; monthly median of the monthly means; harmonic mean; median of the annual 7-day low flow; and the 7-day, 2-year (7Q2), 7-day, 10-year (7Q10), 30-day, 2-year (30Q2), and 30-day, 10-year (30Q10) low-flow frequencies for the 18 sites (7 streamgages and 11 partial-record stations).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P14K6CFV", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.67e6b311d34e9069a3f80e39.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_67e6b311d34e9069a3f80e39", "keyword": ["Cape Code", "Massachusetts", "USGS:67e6b311d34e9069a3f80e39", "groundwater and surface-water interaction", "groundwater flow", "inlandWaters", "stream discharge", "streamflow", "surface water (non-marine)", "water resources"], "modified": "2025-09-19T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-70.9000, 41.5000, -69.9000, 42.2000", "theme": ["geospatial"], "title": "Low-flow Statistic Equations and Supplemental Data for the Plymouth-Carver Kingston-Duxbury Aquifer Area in Southeastern Massachusetts and Cape Cod"}
