There are nascent efforts to get Sacramento River delta farmers to trade in farming in their (thousands of acres of!) sub-sea-level fields for collecting carbon credits by flooding them and letting swamp vegetation settle. Presumably they could also float solar and collect revenue and carbon credits from that, and grow freshwater shrimp, besides. There is a serious worry that in the next big Cal earthquake, dikes will collapse, pulling sea water into the delta. It has happened before. Generally, restoring wetland that had been converted to farmland can be done in many places to similar effect. Floating solar is a big win, producing much more power than the same panel in the desert, and lasting much longer, without interfering with anything else.
