The following information was provided by Masaya Maeda of the Anacostia Watershed Society.

AWS has decided to conduct a SCA (Stream Corridor Assessment) survey on the Northwest Branch and has already conducted it on a small portion of the stream. We would like to identify environmental problems such as eroding stream banks, inadequate stream buffers, exposed pipes, altered stream channels, fish migration barriers, pipe outfalls, in-stream construction sites and trash dumping locations along the branch. The major findings will be reported appropriately. The data will be also used to raise people's awareness of stream problems and eventually it will be incorporated into WRAS project by State Government.

Survey Date: 4/26/2005

Site 223103 Erosion Site
A long stretch in the branch has erosion on one site or the other of the banks.

Incidentally, Montgomery DEP is aware of these erosion sites. As I walk along the stream there are many marks
usually on trees indicating that DEP or MNCPPC is monitoring the stream banks extensively.
The following sentences are sited from e-mail from Montgomery County DEP.

"In cooperation with the Corps of Engineers, we presently have 20 projects under detailed design to address some of the problems
which we jointly determined to be most severe and correctable, based upon feasibility planning studies
the Corps has done for us within the portion of NW branch that lies within Montgomery County."

Someone was playing with this tire in the near past. At the time, this tree must have rooted firmly.
