Ashuelot River site descriptions
When the bank is termed the east side or west side, assume that the river is flowing to the south.
Site 1 Pillsbury park outlet. Upstream from the Rt 31 highway bridge on the east side of the river.
Downstream from the dam that is the outlet of the Pillsbury Park lake system. Samples taken about 100
feet upstream from Rt 31.
Site 1.5 Mountain Road. At intersection of Mountain road and Long Pond Road. Samples taken upstream
from Mountain Road on the east side of the stream. The stream is split by an island at the sample site, and
it is the east branch that is sampled.
Site 2 Marlow downstream from the dam and where the stream is very close to Rt. 10.
Downstream from riffle. Samples taken from near the center of the riffle on the east side of the river.
Site 3 Gilsum downstream from village of Gilsum and upstream from Gilsum Stone Arch Bridge and near
a truck stop or a wide place in the road on Rt 10. In early 2002 there were construction materials and
construction equipment stored there. Samples are taken in fast water near the east side of the river.
