Establishes Office of River Maintenance in DEP; repeals P.L.1993, c.376 concerning stream cleaning activities.

S 1337 establishes a dedicated Office of River Maintenance within New Jersey's Department of Environmental Protection (DEP) to manage river health. This office will oversee all stream cleaning (removing debris/sediment) and bank stabilization projects across state waterways, replacing the previous system under P.L.1993, c.376. Key provisions require projects to preserve historic stream contours, protect vegetation on southern/western banks, coordinate with wildlife agencies near endangered species, and comply with wetlands and flood control laws. The bill directly affects DEP operations, local municipalities managing waterways, and ecosystems in protected waters like trout habitats and Category One waters.
