The main purpose of this legislative proposal is to study the Upper Raritan River Watershed in New Jersey to determine if it should be added to the National Wild and Scenic Rivers System. This designation aims to protect the watershed's natural and cultural resources while promoting conservation efforts. Key provisions of the proposal include the formal designation of specific segments of the North Branch Raritan River, South Branch Raritan River, and the Lamington-Black River, along with their tributaries, for study.
