Record amounts of precipitation fell across the Colorado Front Range from September 9 to 16, 2013, resulting in extensive flooding in the South Platte River and its major mountain tributaries. In this study, the effects of the flood on the City of Boulder, Colorado urban hydrology system were assessed using weekly time-series sampling of 3 source waters (Boulder tap water, Boulder wastewater treatment facility effluent, and Boulder Creek water) conducted from September 20 to October 16, 2012 (n=5) and August 13 to September 30, 2013 (n=8). The effect of the flood on the South Platte River was assessed using a single basin-wide sampling of 5 main stem and 7 tributary sites from September 18 to 22, 2013. Filtered...

In 2004, the U.S. Geological Survey initiated a large-scale regional study of the Denver Basin aquifer system to evaluate the hydrologic effects of continued pumping and document an updated groundwater-flow model useful for appraisal of hydrologic conditions (Paschke, 2011). This data release includes spatial datasets used as input for a three-dimensional groundwater-flow model of the Denver Basin aquifer system. Spatial datasets were developed for six Denver Basin bedrock aquifers and five intervening confining units including, from oldest to youngest, the Laramie-Fox Hills aquifer (KLF), Laramie confining unit (KLC), lower Arapahoe aquifer (LKA), Arapahoe confining unit (KAC), upper Arapahoe aquifer (UKA), Denver...
Near-surface geophysical surveys were completed in September 2020 in a mine-affected drainage near Breckenridge, Colorado, known as French Gulch. The study area was along a 0.3 mile (0.5 kilometer [km]) reach of French Gulch, approximately 2 river miles upstream from its confluence with the Blue River. This data release presents data from three geophysical surveys that used fiber-optic distributed temperature sensing (FO-DTS), forward-looking infrared (FLIR) imagery, and frequency domain electromagnetic induction (FDEM). The FO-DTS data were collected from September 14 to 17, 2020, using a Silixa XT-DTS system (Silixa, 2021) in single-ended mode. The FO-DTS cable was placed along the right and left banks of the...
