Between 2022 and 2024 the U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency, completed synoptic tracer-injection studies and monitored water temperatures to evaluate spatial and temporal changes in connectivity between groundwater and surface water and to understand metal loading. This dataset aids in providing a complete hydrologic and geochemical conceptualization of the processes occurring in the mine workings and adjacent groundwater and serves as an example of applications to other sites.  \nThis child item contains water temperature data used to quantify groundwater discharge to streams and identify zones of groundwater influence over streamflow.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1RPUHAX", "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.685d8dc2d4be02077e8f4d5e.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_685d8dc2d4be02077e8f4d5e", "keyword": ["Cement Creek", "Colorado", "Silverton", "USGS:685d8dc2d4be02077e8f4d5e", "abandoned mines and quarries", "geochemistry", "groundwater quality", "hydrology", "mine drainage", "mineral deposits", "tracer study", "water temperature"], "modified": "2026-07-08T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-107.68559, 37.86103, -107.62928, 37.91116", "theme": ["geospatial"], "title": "Water temperature"}
