To determine if and when the hyporheic zone mediates metal(loid) export, we investigated the relationship between streamflow, groundwater-stream connectivity, and subsurface metal(loid) concentrations in two ~1 km stream reaches within the Bonita Peak Mining District, a U.S. Environmental Protection Agency Superfund site located near Silverton, Colorado, USA. The hyporheic zones of reaches in two streams—Mineral Creek and Cement Creek—were characterized using a combination of flow analysis, salt-tracer injection tests, transient-storage modeling, and geochemical sampling of the shallow streambed (< 0.7 m). The following resource contains raw HOBO Pressure Transducer files and rating curves that were used to create the hydrograph in Figure 8 of the associated publication "Groundwater-stream connectivity mediates metal(loid) geochemistry in the hyporheic zone of streams impacted by historic mining and acid rock drainage." The HOBO files include water and barometric pressure measurements (15min interval) at two locations north of Silverton, Colorado. The locations are near the Chattanooga Fen Complex on Mineral Creek (37.867540°, -107.723876°) and Cement Creek downstream of Prospect Gulch (37.88049°, -107.66814°). Also included are two excel files (one for each stream site) with manual flow measurements and rating curves. The rating curves in combination with the stream stage files (estimated from the pressure transducer measurements) were used to calculate stream discharge. The .hobo files can be viewed in the HOBO software, which is a free download (https://www.onsetcomp.com/hoboware-free-download/).
This archive contains files related to the manuscript, GROUNDWATER-STREAM CONNECTIVITY MEDIATES METAL(LOID) GEOCHEMISTRY IN HYPORHEIC ZONES OF STREAMS IMPACTED BY HISTORIC MINING AND ACID ROCK DRAINAGE by Beth Hoagland, Alexis Navarre-Sitchler, Rory Cowie, and Kamini Singha, for Frontiers in Water. It contains two types of files: 1) HOBO pressure transducer files (.hobo) for barometric pressure (files with _AIR) and stream water pressure (files with _SW). The barometric files should be used to correct the water pressure and estimate stream water levels. The dates of the data download are included in the file name as YYMMdd. 2) Excel files with rating curves for 2019 2020 for each of the two sites (MC Mineral Creek and CC Cement Creek) and manual flow measurements made using a HACH Flow Meter.
