Aerial and Field SAV Observations

I surveyed about 2.5 miles of tidal Mattawoman Creek by kayak on 9-17-11, starting at the kayak launch at the end of Mattingly Road and paddling upstream, not quite reaching the bridge across the creek. The trip included high tide so it was only near the end of the trip that SAV was visible at [...]

Mill Creek on Magothy River had a 3 million gallon sewage spill in its lower nontidal reaches in December 2005, that added a large amount of sediment to its upper tidal reaches. Its uppermost tidal reaches were dredged last winter (2010-2011) to remove some of that sediment and restore the previous boat access. There were [...]

It appears the mahogany tide that has been in the upper Magothy creeks (Cattail and/or Old Man) since 7/5/08 has spread downriver to areas near the SAV beds. My long term monitoring site at Ulmstead/Forked Creek did not have reddish water on 7/18 but it did this [...]
