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: 3/22/2005
Site 207107 Erosion site
Approximate length: 120 ft Approximate average height: 6ft
Site 208102 Erosion site
Approximate length: 240 ft Approximate average height: 5ft
Site 208107 Erosion site
Approximate length: 300 ft Approximate average height: 6 ft
Site 208108 Erosion site
Approximate length: over 581 ft Approximate average height: 6 ft
Is this a stream? Yes, it is. There is no flow because it wasn’t raining when I surveyed.
This is a small stream flowing into NW branch only when it rains. It is suspected that the stream was created
by land use change upstream. The whole stretch of the stream has erosion problem.
I could not go deeper than 581 ft from the main stream because of falling trees and vines including poison ivy.
Site 208110 Erosion site
Approximate length: 400 ft Approximate average height: 6 ft
Site 208112 Erosion site
Approximate length: 120 ft Approximate average height: 6 ft
Site 208113 Erosion site
Approximate average height: 7 ft This is also a small stream flowing into NW branch.
The situation is similar to the
Site 208108. I didn't walk this stream due to the similarity
to the site 208108 and time restriction. Follow-up survey is expected to be done.
Site 208114 Erosion site
Approximate length: 60 ft Approximate average height: 7 ft
Site 209101 Erosion site
Approximate length: 814 ft Approximate average height: 5 ft
Site 209104 Erosion site
Approximate length: 200 ft Approximate average height: 7 ft
