Guess which N.E. headwater this is

[SamRiley]

Was on the road for work yesterday and I find out that the people I was meeting live just up the hill from the headwater of a well known New England Trout river. Can anyone guess which one?

[Chuckster]

Indian Head/North River in Hanover/Hanson?

[SamRiley]

Too far NNW

Hint:
Photo was taken from this bridge...

[Pauper Piscator]

That is the bridge to the athletic fields at a college in Manchester NH I believe.

Merrimac?

[SamRiley]

nope... too far NE

[DAQ]

Sudbury river in Hopkinton.

[SamRiley]

Nope. Set a course of 340-50 or so and you should hit it.

Hint: it's a short river

[Eddy Merckx]

nissitisset or squannacook?

[SamRiley]

Nissitissit it is --127-3-
