Corrine Irwin (Quad 034)
Surveyed the Potomac River from Gravelly Point, along the full perimeter of DCA, through and beyond the Washington Sailing Marina/Dangerfield Island (38.864427, -77.038515 to 38.830060, -77.038029). It was wonderful to see such a thick, lush bed of grasses yesterday!  I’m not sure how far beyond the lat/long I provided it extended. I saw [...]

Terry Willis (Quad 009, 015, 021, 026)

The SAV in Smith Island usually looks pretty healthy, but they looked even better than usual last week. No epiphytes and bright bright green. Zostera and Ruppia!

Here’s a shot I made in the Honga River in May.  There was a thick patch of eelgrass mixed in with widgeon.

Vallisneria seed pods - Susquehanna Flats & Elk River

Mark Lewandowski (003, 010)
I was up in the Flats to check Vallisneria seed pod development. Rogues Harbor had thousands of seed pods, but they were not quite ready for harvest. Also I paddled north out of Tydings Park up to the first bridge and there were Vallisneria seed pods everywhere.
