Groundwater Outreach in Huron, SD

USGS Hydrologist Ryan Thompson demonstrated a groundwater model to a 4th grade class in Huron, SD, on April 2, 2015. Ryan talked about groundwater and aquifers, and led students through several experiments to help them understand and measure the porosity, specific yield, and hydraulic conductivity of three different sizes of aquifer materials. Ryan also used dye in an

Slope-Area Measurements in Northern Black Hills, SD

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. The resulting hydrologic response was noteworthy in
