The data assembled in the CSV originally came from the "Dams" table in the associated USGS Dam Removal Science Database (reference item associations in the ScienceBase item). That table went through a number of offline processing steps that will be formalized into code at a later time to produce a derivative that contained the featureuri reference to dam removals in the Spatial Feature Registry as the persistent identifier used throughout the National Dam Removal Science Database. Final processing steps to produce the initial iteration of a usable standalone table were executed through OpenRefine and are captured in JSON files attached with this ScienceBase item. Those steps removed unnecessary columns where the information is now available in the Spatial Feature Registry and changed column names to provide direct URL references to the ScienceBase Vocabulary where the Dam Removal terms are defined.
