Water-level data and AQTESOLV Pro analysis results for slug tests in the Big Sioux Aquifer, Sioux Falls, South Dakota, 2017

Well and aquifer data were collected from field measurements and drillers’ logs. Multiple slug tests were completed at each well with a transducer to record the change in water level and a U.S. Geological Survey standard mechanical slug to displace the well’s water column. A Solinst Levelogger LT F30/M10 electronic transducer (unvented) was used to record water-level...

High-Resolution Hydrographic Mapping on a portion of the Big Sioux River Basin in Southeast South Dakota, 2016

A High-Resolution Hydrographic Mapping effort was completed for thirteen 12-digit hydrologic units in the Big Sioux River Basin near Sioux Falls in southeastern South Dakota. A digital elevation model based on light detection and ranging (lidar) data was prepared from four sources. Known culverts were hydro-enforced into the elevation model, and selective drainage techniques were utilized...

Time-lapse video of photographs of the Lake Sharpe Shoreline near Lower Brule, South Dakota, 2013-15

A sequence of images were captured automatically from trail cameras placed at three locations along the Lake Sharpe Shoreline near Lower Brule, South Dakota. The images were reviewed, and the best daylight image from each day was selected. The daily images were then displayed sequentially and recorded at 10 frames per second, creating a time-lapse video. The still images and videos in this...

Historical shoreline traces of Lake Sharpe near Lower Brule, South Dakota, 1966-2010

The 1966 USGS 7.5 minute quadrangle map and aerial imagery available for the years of 1991, 2004, 2005, 2006, 2008, and 2010 was used to trace the shoreline of Lake Sharpe near Lower Brule, South Dakota. The Heads-up digitizing in ArcMap was used to trace shorelines from the 1966 quadrangle map and the aerial imagery. The resulting shoreline trace lines were saved in shapefile format. This...

Aerial imagery basemap for the Lake Sharpe shoreline near Lower Brule, South Dakota, captured from an unmanned aerial system, August, 2012

A Raven RQ-11A unmanned aerial system, equipped with an on-board video camera and global positioning system, was used to capture video of a seven mile reach of Lake Sharpe Shoreline near Lower Brule, South Dakota in August of 2012. This dataset is a basemap derived from still images captured from the video, georeferenced using information from the on-board global positioning system and a...
