Team: Gail Sawyer, Larry Lombardo (verbal data) Tom Tidman, Dick Hatfield (written data)

We surveyed the Nashoba Brook from the Westford/Acton town line to a point approximately 3000 feet downstream. Gunfire at the Nashoba Sportsmen's Club limited our observations to southeast of this point. The stream is 6 to 24 inches deep, 10 to 15 feet wide and flowing moderately. Banks are heavily vegetated. Water quality appears to be good, with the exception of a section next to the piggery, where the odor of garbage is pervasive. A long abandoned railroad grade parallels the brook and appears to be getting regular use by hikers, horses, and some ATV's. The only area of concern on this section is turbidity/nutrient loading near the piggery.
