Description: HYD_AREA_POLY: This dataset contains area 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) hydrography event data. This dataset will be refreshed as-needed to reflect updates to the NHD and Bureau of Land Management (BLM) hydrography event data.
