USGS researchers running slope-area measurement in Ward Draw following storm of August 5, 2014. A group of thunderstorms produced greater than 4 inches of rain during four periods of progressively more intense rainfall across a small part of a relatively high-elevation area of the northern Black Hills on August 5, 2014.

Water-quality data and trends in the Rapid Creek Basin, South Dakota, 1970–2020
Surface-water-quality data in the Rapid Creek Basin in South Dakota were compiled to assess basic trends in the water quality of Rapid Creek. Spatial and temporal patterns in water quality were described for major ions, sediment, total suspended solids, nutrients, field measurements, bacteria, and select metals for the period of 1970–2020, and a water-quality trend analysis was completed for sitesAuthorsWyatt S. Tatge, Galen K. Hoogestraat, Rochelle A. NustadBorehole analysis, single-well aquifer testing, and water quality for the Burnpit well, Mount Rushmore National Memorial, South Dakota
Mount Rushmore National Memorial (hereafter referred to as “the memorial”), in western South Dakota, is maintained by the National Park Service (NPS) and includes 1,278 acres of land in the east-central part of the Black Hills. An ongoing challenge for NPS managers at the memorial is providing water from sustainable and reliable sources for operations, staff, and the increasing number of visitors.AuthorsWilliam G. Eldridge, Galen K. Hoogestraat, Steven E. RiceStormwater quality of infrastructure elements in Rapid City, South Dakota, 2016–18
As runoff flows over the land or impervious surfaces (paved streets, parking lots, and building roofs), it accumulates debris, chemicals, sediment, and other contaminants that can adversely affect water quality if the runoff discharge remains untreated. Pathogens, commonly measured using fecal indicator bacteria such as Escherichia coli, enterococci, or fecal coliform, are the most-frequent causeAuthorsGalen K. Hoogestraat - Science
