It drains a mountainous region of the northern Allegheny Plateau in the Southern Tier of New York.
In the colonial times the river valley was a major trade route through the hill country of western New York, first for the Iroquois and other Native Americans, and later for the European settlers.
Although the river is no longer used for transportation, it has become a popular destination for recreational canoeing and fly fishing, in particular for smallmouth and largemouth bass, trout, rock bass, sunfish, bluegill, and carp.
The aquifer occupies four deeply incised bedrock valleys formed by the junction of the Chemung River and its principal tributaries, the Canisteo, the Tioga, and the CohoctonRivers, in southeastern Steuben County, N.Y. fig.
The Little Androscoggin River Valley aquifer is an example of a valley-fill glacial aquifer deposited by meltwater streams that flowed away from stagnated or melting glacial ice in lowland bedrock valleys that were either partly or completely inundated by the ocean.
Thus, precipitation that falls on the Little Androscoggin River aquifer and the surrounding basin area is the source of all water in the basin.
