Chemical data from stream water, groundwater, and soil samples collected in 2019 and 2020 in this area. Data from a tracer study is included as tool for understanding sources and loading rates of metals affecting stream water quality in a watershed affected by legacy mining and natural sulfide-weathering. Data are provided in CSV format.

To help understand the hydrogeologic controls in the basin and how they affect surface and groundwater interactions with nearby mine workings, electrical resistivity profile, self–potential, and magnetic measurement data are provided herein.

Releases airborne survey data, resistivity cross-sections and depth slices derived from data inversion. Resulting resistivity models confirm geologic framework, constrain hydrostratigraphy and depth to basement, and reveal fault and fold distribution.

Geological and borehole geophysical data and observations collected to characterize the basin and its surface and groundwater flow systems with primary focus on the physical characteristics of the fault vein, related mine workings, and surrounding bedrock

The objective of the survey was to improve the understanding of the relationship between surface water and groundwater systems critical to developing management programs for water resources.

Geophysical surveys to map shallow hydrogeologic features of the southwestern part of the Sand Hills that contain a mix of fresh to saline lakes.

The objective of the contracted survey was to improve the understanding of the relation between surface water and groundwater systems critical to developing groundwater models used in management programs for water resources.
