{ "currentVersion": 10.91, "id": 1, "name": "USGS Streamflow Gauge 7-day minimums", "type": "Feature Layer", "description": "This layer displays empirically derived low flow metrics from sites with continuous USGS flow gauges. Data are displayed for two commonly used low flow statistics, 7Q2 and 7Q10, which is the minimum seven-day mean streamflow (cfs) that occurs every two, and ten years, respectively. \nUSGS gauges in Wisconsin were found by downloading the \u201cUSGS Gage Stations\u201d available on the WDNR Surface Water Data Viewer. For each USGS gage daily streamflow data were download using the dataRetrieval (v2.7.4) R package on August 6th, 2018. Data are available for each metric if the minimum required data exists (i.e. two years of record for 7Q2 and ten years for 7Q10). A full year of record was limited to years were at least 325 daily streamflow measurements were recorded. However, users should beware that values calculated from the minimum required data maybe unreliable depending on the specific weather patterns in that timeframe. Gauges with three times the minimum required data (i.e. six years for 7Q2 and 30 years for 7Q10) will likely provide more reliable estimates. 7Q2 and 7Q10 estimates are available for the majority of stream reaches on the Wisconsin Hydrography Database estimated from USGS \u201cLow-Flow Characteristics of Streams\u2026\u201d USGS Water Resource Investigations, or WDNR calculations created using the USGS methods. See the HYDRO_VA_7QX_Flow layer available on the WPDES Viewer for these additional low flow metrics. \n", "geometryType": "esriGeometryPoint", "sourceSpatialReference": {"wkt": "PROJCS[\"NAD_1983_HARN_Transverse_Mercator\",GEOGCS[\"GCS_North_American_1983_HARN\",DATUM[\"D_North_American_1983_HARN\",SPHEROID[\"GRS_1980\",6378137.0,298.257222101]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Transverse_Mercator\"],PARAMETER[\"False_Easting\",520000.0],PARAMETER[\"False_Northing\",-4480000.0],PARAMETER[\"Central_Meridian\",-90.0],PARAMETER[\"Scale_Factor\",0.9996],PARAMETER[\"Latitude_Of_Origin\",0.0],UNIT[\"Meter\",1.0]]"}, "copyrightText": "Ben Kort, Mike Shupryt, WQ Bureau", "parentLayer": null, "subLayers": [], "minScale": 10000000, "maxScale": 1, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriPMS", "url": "c80e8c0fe154bf23571791c6fe0937d9", "imageData": "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", "contentType": "image/png", "width": 9, "height": 8, "angle": 0, "xoffset": 0, "yoffset": 0 }, "label": "", "description": "" }, "transparency": 0, "labelingInfo": null }, "defaultVisibility": true, "extent": { "xmin": 298352.2401727068, "ymin": 226362.22327551153, "xmax": 714394.2669048824, "ymax": 714487.2859462453, "spatialReference": { "wkid": 3071, "latestWkid": 3071 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "STATION_ID", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "SHAPE", "type": "esriFieldTypeGeometry", "alias": "SHAPE", "domain": null }, { "name": "STATION_ID", "type": "esriFieldTypeString", "alias": "Station Id", "length": 50, "domain": null }, { "name": "F7Q2_EMPIRICAL", "type": "esriFieldTypeDouble", "alias": "7-day, 2-year low flow (cfs)", "domain": null }, { "name": "F7Q10_EMPIRICAL", "type": "esriFieldTypeDouble", "alias": "7-day, 10-year low flow (cfs)", "domain": null }, { "name": "F30Q5_EMPIRICAL", "type": "esriFieldTypeDouble", "alias": "30-day, 5-year low flow", "domain": null }, { "name": "F1Q10_EMPIRICAL", "type": "esriFieldTypeDouble", "alias": "1-day, 10-year low flow", "domain": null }, { "name": "ANNUAL_BASEFLOW_AVG", "type": "esriFieldTypeDouble", "alias": "Annual Baseflow Average", "domain": null }, { "name": "YEARS_OF_RECORD", "type": "esriFieldTypeInteger", "alias": "Years of Record", "domain": null }, { "name": "LAST_YEAR", "type": "esriFieldTypeString", "alias": "Last Year", "length": 5, "domain": null }, { "name": "FIRST_YEAR", "type": "esriFieldTypeString", "alias": "First Year", "length": 5, "domain": null }, { "name": "GAGENAME", "type": "esriFieldTypeString", "alias": "Gage Name", "length": 255, "domain": null }, { "name": "DRAINAGEAREA_MI2", "type": "esriFieldTypeInteger", "alias": "Drainage Area mi2", "domain": null } ], "geometryField": { "name": "SHAPE", "type": "esriFieldTypeGeometry", "alias": "SHAPE" }, "indexes": null, "subtypes": [], "relationships": [], "canModifyLayer": true, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 1000, "supportsStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, geoJSON", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsHavingClause": true, "supportsCountDistinct": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsPagination": true, "supportsTrueCurve": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": true }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "supportsCoordinatesQuantization": true }
