Annual peak-flow data from the 1844 - 2013 water years were used in the study (U.S. Geological Survey, 2024).  Following federal guidelines for flood-frequency analysis (Bulletin 17C; England and others, 2018) and methods outlined in recent flood-frequency reports for the region (Eash and others, 2013; Southard and Veilleux, 2014; Levin and Sanocki, 2023; Sanocki and Levin, 2023), the Expected Moments Algorithm (EMA) was used in version 7.5.1 of USGS PeakFQ software (Veilleux and others, 2014; Flynn and others, 2006; https://water.ugsgs.gov/software/PeakFQ/) to conduct the analyses.  Results of the analyses, specifically the at-site skew and its mean squared error, are intended for use in Bayesian weighted least-squares/Bayesian generalized least-squares (B-WLS/B-GLS) regression (Veilleux and Wagner, 2019; Veilleux and Wagner, 2021) to model regional skew for the study area.  Peak-flow (.pkf), specification (.psf), output (.PRT), and export (.EXP) files from PeakFQ and a .csv file containing site information and selected results of flood-frequency analyses are provided.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1QWRRAQ", "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.671ab438d34efed5620fbdde.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_671ab438d34efed5620fbdde", "keyword": ["Illinois", "Indiana", "Iowa", "Kansas", "Minnesota", "Missouri", "Nebraska", "North Dakota", "Souris-Red-Rainy Region - 2-digit Hydrologic Unit Code - 09", "South Dakota", "USGS:671ab438d34efed5620fbdde", "Upper Mississippi Region - 2-digit Hydrologic Unit Code - 07", "Wisconsin", "annual exceedance probability", "flood estimates", "flood frequency", "hydrology", "inlandWaters", "peak flows", "regional skew"], "modified": "2025-03-14T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-103.7640, 36.9380, -85.8740, 49.3750", "theme": ["geospatial"], "title": "At-site flood frequency for 422 streamgages in parts of the Upper Mississippi and Souris-Red-Rainy basins and surrounding areas in the United States, using data through water year 2013"}
