California growing regions: water history timelines

How did each California growing region get its water, and what rules now shape it? Pick a region, past or present, to see researched timelines on a shared axis: supply development, demand factors, groundwater regulation, surface-water and interstate water rights, state and federal environmental water-supply law (with Delta and species decisions documented), and a separate endangered-species history track, each shown where it applies. Toggle or overlay the layers; labels auto-stack so nothing collides; click any event for an on-page background briefing.
