We are very fortunate to have Mass Audubon Society’s Drumlin Farms Educational Department as an integral part of our Network. These reports were submitted by Sally Farrow following different visits to different sites by different schools.
The following is data from three different points on the Assabet, Sudbury and Concord Rivers with three different schools:
The data collected with the Forest Ave and Mulready Schools is part of the River Schools program. We explored the forest and riparian zone along the river as well as investigating the macroinvertebrates and water chemistry of the Assabet River
Assabet River, Mulready School 1st grade, Wood Park, Hudson MA 4/15/2014
Weather: cloudy with some drizzle
Water Measurements: temperature was 65 F, pH= 7 and Dissolved oxygen was 4.5 ppm
Animal Life: Macroinvertebrates and other aquatic species discovered by the students: bullfrog tadpole, scud, isopod, damselfly nymph, mosquito larva, diving beetle, and painted turtles. The data indicates that the Assabet is a healthy river.
Along the wooded trail the students observed at least 13 species of plants, evidence of beaver, 27 bird species, grey squirrels and moths indicating wonderful biodiversity in this riparian habitat.
Assabet River, Forest Avenue School 4th graders , Hudson, 5/2/2014: Later in the spring 5/2/2014 and upriver from Wood Park on the Assabet, the 4th graders from the Forest Ave School explored the Assabet and its related habitat:
Weather: sunny
Water Measurements: temperature: 50 F, pH = 6.5, Dissolved oxygen was 4.5 ppm. The water was clear.
Animal Life: Macroinvertebrates: mayfly, water strider, midge, predacious diving beetle, caddis fly, damsel fly, amphipod, springtail, fishing spider. Again the biodiversity indicates a healthy river
Along the river in the riparian zone which was mostly forested, the students observed grey squirrels and a mole and evidence of beaver and raccoon. They also saw at least 29 species of plants , 17 species of birds and 5 different insects. Again everyone had a wonderful time discovering the amazing richness of the Assabet River watershed.

Sudbury River, Cameron Middle School 7th Graders, Framingham
On 5/27/2-5/29/2014 the students of the Cameran Middle School 7th graders in Framingham explored the Sudbury River and the surrounding habitat.
Weather: We had 2 sunny days and one very rainy day.
The students explored watersheds, oxbows, flood plains, energy flows through a riverine ecosystem, human impacts on watersheds and water quality. We learned how to assess the health of a river through water testing, macroinvertebrate studies, and observation of indicator species
Water Measurements: The pH of the water was measured at 6.5
Animal Life: Macroinvertebrates and other aquatic species observed: scud, damselfly nymph, backswimmer, snail, leech, whirligig beetle, dragonfly. Also observed, pickerel, leopard frog and painted turtles and a northern water snake
We also observed at least 12 different species of birds and plants.
Thank you to Kathleen Regan who compiled this data
Concord River, Summer Compass Program, Lowell High School, Lowell MA, 7/17/2014
Concord River at the Concord River Greenway (CRG) in downtown Lowell MA. The students of the Summer Compass Program at Lowell High School visited the Concord River on 7/17/2014 and gathered this data.
Weather: partly sunny air temperature: 23 C water temperature: 25 C
Water Measurements: pH = 7.5-8, dissolved oxygen 5-6 ppm, phosphates 1-1.5 ppm, nitrate 0 ppm, jtu = 0
Animal Diversity: macroinvertebrates: scuds, planaria, beetle larva,, black fly larva, mussel, water striders, stonefly larva, fingernail clam, adult caddis fly, fishing spider, damselfly larva. We also observed a turtle (probably a painted turtle although a wood turtle was spotted in one of the canals!)
The students also saw a great blue heron, kingfisher and kingbird. River birch, silver maples, and red maples were also noted.
The students enjoyed the cool breeze the river provided in downtown Lowell and we were all thrilled to see the biodiversity of the river and the good river chemistry.
Concord River, Spindle City Core Students, 8/8/2014
On 8/8/2014 the SCC students (Spindle City Core) visited the CRG at Lawrence St.
Weather: sunny Air temperature: 22.5 C Water Temperature 23.5 C
Water Measurements: pH = 7.5, DO = 8 ppm, phosphate = 0 ppm, nitrate = 0 ppm
Animal Life: Macroinvertebrates: scud, fingernail clam, snails, leech, water striders, caddis fly larva, beetle larva, planaria. A small green frog
Our SCC students had a great time at the river exploring all it has to offer. They also did some eel monitoring while they were there. They were pleased to note the good health of the river just prior to the confluence with the Merrimack.
Thanks to all these students for their fantastic observations of our watershed!
