The river's watershed covers 2,600 square miles and includes several reservoirs and dams, including the Chemung River Dam and the Harris Hill Dam. These structures help regulate the river's flow and provide water for agricultural purposes. In recent years, the Chemung River has seen improvements in water quality and wildlife habitat due to conservation efforts by local organizations.
