The name of the Cowanesque River is of Native American origin, derived either from Go-wan-is-que ("briary or thorn bushy"), or from Ka-hwe-nes-ka ("on the long island").^[4]

In Tioga County, the Cowanesque Dam was constructed by the US Army Corps of Engineers in 1980. The dam created Cowanesque Lake, which helps prevent flooding within the valley. The 1,085-acre (4.39 km²) lake also facilitates various forms of recreation; the Tompkins Recreation Area and Campground is located along the lake's north shore, and the south shore hosts two day-use areas.^[5]
