The river is named after the volcanic trap rock formations found along its banks. The river's hydrology is heavily influenced by human activity, with several reservoirs and dams constructed along its length to provide drinking water and hydroelectric power. Some of the major reservoirs include the Shuttle Meadow Reservoir and the New Britain Reservoir. The river also supports recreational activities such as fishing, kayaking, and hiking, as well as agricultural uses such as irrigation. Despite the impacts of human activity, efforts are being made to improve the river's water quality and biodiversity through restoration projects and conservation efforts.
