- Description:
Seven Major Watershed Boundaries, Santa Barbara County, California.
A "Select by Attributes" was performed to select the six major HUC 8 boundaries in Santa Barbara County buffered boundary:
- Central Coastal
- Cuyama
- San Antonio
- Santa Barbara Coastal
- Santa Maria
- Santa Ynez
Two HUC 12 watershed boundaries were selected and dissolved to form the seventh major watershed boundary:
The Watershed Boundary Dataset (WBD) defines the areal extent of surface water drainage to a point, accounting for all land and surface areas. Watershed Boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. The intent of defining Hydrologic Units (HU) for the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. At a minimum, the WBD is being delineated and georeferenced to the USGS 1:24,000 scale topographic base map meeting National Map Accuracy Standards (NMAS). Hydrologic units are given a Hydrologic Unit Code (HUC). For example, a hydrologic region has a 2-digit HUC. A HUC describes where the unit is in the country and the level of the unit.
