Field notes
The groundwater section links to monthly briefings by groundwater sustainability agency, a track record, data releases, a model card, and an API. The surface-water section separates delivery, tributary, and Southern California delivery maps. Each map’s Cite button includes a frozen release ID and date; the page states that outputs use CC BY-NC 4.0, with specified commercial-use exceptions for public agencies, groundwater sustainability agencies, their consultants, and academic researchers.
