资源简介：
This dataset represents the region of hydrological influence (RHI) for National Wildlife Refuge System lands. RHI is defined as the area that is most likely influencing the hydrology and water quality encompassing the refuge. Many of these boundaries are merged USGS unique hydrologic units (e.g., HUC-6, 8, 10, 12) or generated using hydrologic modeling techniques.
