Description: The Local and Subregional Drainage Basin Direction layers are cartographic data products. These point feature must be used with the appropriate drainage basin polygon and line feature data. They must not be depicted on maps as simple point symbols without symbolizing them with arrows that take on the appropriate direction. Theses arrows are meant to indicate where one basin drains into another and are intended aid in visualizing the network of subregional drainage basins. They do not depict the exact location of basin outlets.
