Ground water

Stratified glacial deposits in stream valleys form the best aquifers in the Millers River basin. The largest area of glacial outwash was deposited in a glacial lake located near Orange. Meltwater streams deposited sediments, up to 200-ft thick, into this lake.

Other areas capable of yielding moderate to large amounts of ground water to wells occur near the mouth of the Millers River in Millers Falls, along the West Branch Tully River northwest of Athol, along the Otter River and Trout Brook, and in the Winchendon area.
