Each feature class or feature dataset is in Geographic (GCS) NAD83 unless otherwise noted
This dataset contains water body data within the geographic area depicted by the aquatic boundary in the John Day Resource Management Plan. The Hydro Lakes layer consists of bays, lakes, ponds, wetlands, reservoirs, inundation areas, the double lined portions of streams and other hydrographic features best represented as areas.
The intended use of this dataset was for analysis in the John Day Resource Management Plan. This dataset was derived from the Washington and Oregon Framework Hydrography data and the standard system used to identify the states' surface water. The system was developed to provide a standard for referencing surface water bodies and watercourses, and to provide a vehicle for cross-referencing existing surface water data between agencies and groups in both GIS and tabular formats.
