As a first step to building further integrated water management spatial data infrastructure, the CCSC recommends the creation of a universal ID system that assigns standardized numeric identifiers to California’s water entities. Federal Information Processing Standard (FIPS) code equivalents should be mandatory for all state water management agencies. These codes would create a unique spatial identifier that would be linked to U.S. census designated geographies. The FIPS code field would allow for different data, in different formats or platforms, to be linked, and could be used to “join” or “relate” spatial and non-spatial water use data information. This information could also be transferrable into other databases that use FIPS codes, and their fixed IDs would be traceable across platforms.
