Each feature class or feature dataset is in Geographic (GCS) NAD83 unless otherwise noted
HYD_PUB_FLOWLINE: This dataset contains flowline features from the US Geologic Survey (USGS) High Resolution National Hydrography Dataset (NHD). NHD Flowline features are linear depictions of streams and centerlines of rivers. Additional attributes have been added from the Bureau of Land Management (BLM) Aquatic Resources Information Management System (ARIMS) and from the BLM's Land Ownership Polygon layer. The statewide version of this dataset does not include species-specific fish distribution information. Species-specific fish data is only included on the individual subbasin distributions of the data. This dataset will be refreshed as-needed to reflect updates to the NHD and ARIMS.
This publication format is intended to improve the usability of the High Resolution NHD and ARIMS by combining attributes from both sources into one dataset with a simplified structure. The publication format includes the most commonly used attribute information. Other less commonly used attributes are available directly from the ARIMS system.
