Agricultural Subsurface Drainage Tile Locations by Permits in South Dakota

Dataset contains locations of drainage tile permits in South Dakota obtained from County and Local Water Board records. The counties included are: Brown, Deuel, Grant, Hamlin, Hanson, Kingsbury, Lake, McCook, Minnehaha, Moody, Roberts, Spink, and Turner. The date permits records were collected vary by county. A majority of the permits from counties were collected as of January 2012. Two counties (Hanson and Minnehaha) were updated in December,2013. In addition to the location (as a TRS) and available (if given)pipe information recorded on the permit, this dataset provides the latitude and longitude of the location given on the permit, which is not typically provided on the permit application or record. Additionally, overlap of permit polygons (if depicted in a geospatial application) is possible from two permits that share the same area. Permit applications that were: denied, applied to small tracts of homes (home drainage systems), residential subdivisions, ditches, maintenance, or had incomplete TRS information were removed from this database.
