August update on SAV in St. Mary’s River

I paddled from St. Mary’s College south, surveying shore from north of Chancellors Point, around Rosecroft Point, across to Windmill Point and along parts of the western shore back to the college. While not nearly as much SAV as in 2013 (as shown in the Google Earth image) there was widgeon grass from just southeast of Chancellors Point (see yellow marker) around Rosecroft Point to at least the area indicated by the green marker. The distribution was patchy and in shallow water (mostly 0.25 to 0.5 m MLW) but with deeper patches southeast of Chancellors Point. Plants with flowering shoots were largely in the shallower patches. The red markers indicate the location of the largest clump of flowering shoots. I did not see SAV at Windmill Point or along the western shore of the upper river. There was widgeon grass drifting with the tides and in the wrack around Chancellors Point, although not as much as I typically see this time of year.
