Summary

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 digitial 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 within geographic information systems software to identify additional locations where bridges or culverts needed to be hydro-enforced. These potential locations were given a preliminary screening using aerial imagery, and likely locations were further screened using high-resolution oblique aerial imagery or with site visits. Locations with confirmed [...]
