View metadata for key information about this dataset. Data is hand digitized from georeferenced map scans by PWD Office of Watersheds staff. Ellet stream data is supplemented by stream features in the center city area from a GIS layer developed before 2005, which had no metadata. The Historic Streams polygon layer also has an associated arc layer. For questions about this dataset, contact [e-mail].
