The highest EC values occur near the mouths of stream draining settled areas at the south of the lake. (view Stream Map)

Note the higher EC values for streams on the west side of the lake than on the east side of the lake and, in general, that pH values for streams are lower than values for Sandy Lake (see also figure above) except for Bob’s Brook (at southwest corner of the lake) and Peverill’s Brook flowing to Marsh Lake.
