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.

Automated sampler bottles containing stormwater runoff from the Arrowhead drainage basin in Rapid City, SD, being processed in the laboratory. Stormwater runoff from urbanized lands is known to harm surface-water resources by increasing stream velocities, destroying natural habitat, and increasing pollutant loads in the receiving waters.
