The river is fed by several tributaries, including the Shetucket River and the Indian River. The nearby Taftville Dam also affects the flow of the Yantic. Seasonally, the river experiences fluctuations in flow, with peak flows occurring in the spring and fall.

Today, the river is a popular spot for fishing and kayaking.
