Ongoing Stream Survey

The Acton Stream Teams, in cooperation with the Acton Conservation Commission, are sponsoring an Ongoing Stream Survey. Here is the information about how to take part in the Ongoing Survey.
As part of this effort, photos have been taken by volunteers at:
Conant Brook Fort Pond Brook Grassy Pond Brook Inch Brook Nashoba Brook & Robbins Mill Pond Pratt’s Brook Unnamed tributary to Nashoba Brook, near Ice House Pond Will’s Hole Brook
These photos tell a story. For example ones that were taken from the same location looking both upstream and downstream, 4-6 times per year, show the same landmarks, but dramatic seasonal differences in foliage and to some extent in water flow. Photos taken year round, as well as observations made over two years, are evidence that Will’s Hole Brook is a perennial stream. (Click here to see photos.)
Other photos have been valuable in documenting stream conditions and problems such as the overgrowth of duckweed seen in parts of Nashoba Brook and Robbins Mill Pond. This overgrowth is a sign of nutrient enrichment that could lead to other problems, such as unpleasant odors, and oxygen depletion for fish, etc. Sources of excess nutrients, locally and upstream, can include fertilizers from lawn runoff, yard debris near the waterway, faulty septic systems, water fowl, pet wastes, etc. (see photos below)

Taking stream photos periodically can also be a good excuse to take a break from the ordinary routine, and go for a walk. Maybe there’ll be a bird, frog, turtle, deer, or other form of wildlife that you’ll be able to catch on film and share with others. See photos by other local photographers.
	There must be a frustrated beaver near Nashoba Brook in the Nashoba Brook Conservation area: This tree didn’t fall over because its upper branches were caught in place.
Stream photos can be sent at anytime of year to: Department of Natural Resources Acton Town Hall 472 Main Street Acton, MA 01720 Or contact the Acton Stream Teams directly at info@actonstreams.org
