We refer to the lower Yellow River as the section of the Yellow River that extends from its mouth at Blackwater Bay to the Santa Rosa-Okaloosa County line. Today we boated the very lowest part of the lower Yellow River, mostly on the branch called the Weaver River. Here on the lower Yellow River, the water is so acidic that even R. serrulatum thrives. At this time of year, most of the plants were full of flowers. R. austrinum bloom exclusively white to pink here on the lower Yellow River. These, of course, had long since faded and some were showing thick fruit. The first yellow-flowered plants appear only when one gets closer to the county line. We know of exactly two such plants so far. But we didn’t go that far upstream today. We rather started at a boat ramp in the village of Bagdad at the mouth of the Blackwater River, crossed Blackwater Bay and then boated on different river branches in the delta area of the Yellow River. At the “Old Land Place” we had a short shore excursion. Afterwards we spent some time in the estuary of Weaver Creek, which forms beautiful small lakes here. After that we went back to Bagdad.
