[Public-List] Antifouling skirts.

[Mike Lehman]

In the Magothy, we take water quality tests every other week. It shows that there is between 3-6 PPM for salinity. That is basically fresh water. I think the dividing line, which 30 years ago was at Poole's Island, is now down between Deale and Solomons.
