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

Abundance of Chesapeake Bay’s underwater grasses rises 21% in 2015

April 28th, 2016 · Posted by admin· No Comments

An annual survey led by researchers at the Virginia Institute of Marine Science shows that the abundance of underwater grasses in Chesapeake Bay increased 21% between 2014 and 2015, an upsurge from 75,835 acres to 91,621 acres, which represents the highest total of the last 3 decades and just under half of the baywide 185,000-acre restoration goal.

Vallisneria seed pods - Susquehanna Flats & Elk River

September 22nd, 2015 · Posted by admin· No Comments

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.

Tremendous amount of SAV in Potomac

August 11th, 2015 · Posted by Jeff Talbott· No Comments

Jeff Talbott (039, 047, 055)

We have seen a tremendous amount of SAV in the tidal Potomac embayments in Virginia this year. In Quantico Creek, the embayment is about ½ covered with SAV this year. Hydrilla, Eurasian watermilfoil and a few others. Aquia Creek has a large bed near the mouth and beds near the shores all the way up the embayment. In the upper embayment it is covered with SAV and lillypads. Belmont Bay has a large bed about a mile inside the embayment. This bed was also present last year.

Ruppia in the Choptank River, Maryland

August 19th, 2014 · Posted by admin· No Comments

Roby Hurley (Quad 044, 051)

There was a decent population of pondweed in the Tred Avon in early summer but it is mostly gone now. Recently, there has been a good abundance of Ruppia, in the lower Choptank on the Cook Point side (N38 37.245′ W76 16.512′). It must be dispersing now because there was a lot of it floating out in the Bay.

August update on SAV in St. Mary’s River

August 12th, 2014 · Posted by admin· No Comments

Chris Tanner, SMCM (Quads 080)
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.

Thick SAV near Smith Island

August 7th, 2014 · Posted by admin· No Comments

Lee Karrh, MD-DNR (Quad 091)

We were out surveying around Smith Island Monday and Tuesday.  The widgeon grass was amazingly thick in Lightning Knot and Back Coves, with excellent water clarity.  At Fog Point, the eelgrass looked good in that bed on the northern Kedges Strait side of the Island.

No SAV in St. Mary’s River

July 29th, 2014 · Posted by admin· No Comments

Lee Karrh, MD-DNR (Quad 080, 089)

Yesterday, we found virtually no SAV on the St. Mary’s.  We visited Windmill Point, Cherryfield Point, and many areas along the St. George Creek side of St. George Island.  Places that last year had abundant widgeon grass are now bare bottom. Brooke found one tiny area with a few sprigs at Windmill Point.  Becky noted that the ConMon data did show that the creek has been more turbid of late.

Widgeon Grass near Cedar Island

July 25th, 2014 · Posted by admin· No Comments

Ken Schultz (Quads 100, 101)

I’ve encountered large amounts of SAV on two successive trips in the Bay this week, both in the same area of Maryland. This is around Cedar Island, in Fishing Creek, and Crooked Creek and that general vicinity, just north, northeast of Great Fox Island. Dense stands of widgeon grass, coming almost to the surface (the water is clear) on high tide in some places.
