This data set was clipped using ESRI ArcGIS to show only the DLG hydrography lines in the Waianae moku on the Hawaiian Island of Oahu. It was clipped from the state coverage entitled DLGHYDLN that displays hydrography lines on the eight main Hawaiian Islands.
The original data was digitized into ArcInfo coverage format from 1983 USGS DLGs showing hydrography lines on the eight main Hawaiian Islands. It is unknown when the original coverage was digitized.
