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: 4/12/2005

Site 217106 Exposed pipe (manhole stack)
This is not so severe but is in the process of crumbling.

Site 217108 Exposed pipe (manhole stack)
This manhole stack is in the middle of "ghost" stream. The ghost stream appears when it rains.
It assaults this manhole stack. On sunny days it is just a very small stream.

in the middle of the small stream.
The evidence of attack from stormwater.
There is a crack in it.

Site 217128 Fish barrier
This dam is called Burnt Mills Dam.

The height is approximately 40 feet. No fish can go upstream from here.
However, there are some natural fish barriers downstream from this dam.
So, even if we remove this dam the effectiveness of the fish barrier removal may not be so significant.

This dam is silted up.
