Description: The polygon features within this dataset represent the extent of watersheds within the Sonoma County Hydro Enforcement study area. Watersheds are defined based on drainage area and confining topography, and are classified according to the existing Hydrologic Unit Codes (HUC). Watersheds were digitized using vectors and rasters derived from LiDAR data acquired for the NASA ROSES Sonoma County LiDAR and Imagery Survey (2014). The projection is California State Plane (CASP) 2, the horizontal datum is NAD83 (2011), the vertical datum is NAVD88 (Geoid 12A), and the units are US Survey Feet.
