RWQCB Office Areas

To provide a visual image of the administrative boundaries of the Regional Water Quality Control Boards in California, including sub-regional offices, for use in business and reports. The Regional Board Offices layer shows the jurisdictional boundaries of the nine California Regional Water Quality Control Boards (RWQCB) and their sub-regional offices. The RWQCB juridictions are defined in California Water Code Section 13200 and are generally conterminous with the major surface water hydrologic basins of the state. The Regional Board Offices dataset has been compiled from sources (primarily the Calwater v.2.2.1 dataset) at 1:24000 scale.
