This bill, titled the Mullica River Watershed Wild and Scenic River Study Act of 2026, proposes to amend the Wild and Scenic Rivers Act. Its primary purpose is to designate the Mullica River watershed in New Jersey for a comprehensive study to determine its eligibility for inclusion in the National Wild and Scenic Rivers System. The study area specifically includes the Mullica River, Wading River, Batsto River, and numerous detailed segments of their tributaries. The legislation mandates the Secretary of the Interior to conduct and complete this assessment. The study must be finalized and its results reported to the House Committee on Natural Resources and the Senate Committee on Energy and Natural Resources within three years of funds becoming available. This process aims to evaluate the outstanding remarkable values of these river segments for potential federal protection.
