For the purpose of this compilation, \ngroundwater discharge to streams consists of base-flow, and may include contributions from \ngroundwater discharge from various flow paths, lateral seepage, hyporheic flow, and irrigation \nreturn flow. Stream reaches from the National Hydrography Dataset (NHD) where there was \ngroundwater discharge estimates were delineated in the geospatial database. Attributes \ndescribing the methods used for estimating groundwater discharge were created. Feature \nclass attributes associated with each stream reach include: groundwater discharge (acre-ft/yr), \nmethod of measurement, report reference, defined reach, base flow index estimate (acre-ft/yr), \nand 8-digit HUC(s) (hydrologic unit code(s) for the reach). In addition, groundwater discharge \nestimates were calculated using attributes from a flow characteristics dataset (Wolock, 2003), \nthe average annual base-flow index (BFI) value and the average daily streamflow value. The \ncalculated groundwater discharge estimates were  included in the database as separate \nattributes and were compared to reported estimates of groundwater discharge. Groundwater \ndischarge estimates calculated using BFI were greater than reported groundwater discharge \nestimates.\nReferences cited:\nWolock, D., 2003, \nFlow Characteristics at U.S. Geological Survey Streamgages in the Conterminous United States: \nU.S. Geological Survey Open-File Report 2003-146, accessed July 2, 2012 \nat https://water.usgs.gov/GIS/metadata/usgswrd/XML/qsitesdd.xml", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9L6SIZ6", "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.41515e5c-886a-4ea5-9238-5360e6f4d7fa.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_41515e5c-886a-4ea5-9238-5360e6f4d7fa", "keyword": ["Arizona", "Base flow index", "Colorado", "Groundwater discharge", "InlandWaters", "New Mexico", "USGS:41515e5c-886a-4ea5-9238-5360e6f4d7fa", "United States", "Upper Colorado River Basin", "Utah", "Wyoming"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-112.334445, 36.649239, -105.584144, 43.371666", "theme": ["geospatial"], "title": "Geodatabase of Groundwater Discharge Estimates to Streams in the Upper Colorado River Basin"}
