Water Resources

It is the mighty river that roars forcefully, the babbling brook that murmurs its lullaby, the aquatic life below the surface that we protect, preserve, and manage; because without it life could not endure.

WRD Division Brief

Protecting Water

The Water Resources Division (WRD) is one of eight divisions that make up the Natural Resource Stewardship and Science (NRSS) Directorate of the National Park Service. WRD was established to provide servicewide program management and specialized advice and assistance to parks in the protection and management of water resources. The division is comprised of four branches: Aquatic Systems, Ocean & Coastal Resources, Planning & Information, and Water Rights.

The Water Resources Division (WRD) exists to ensure that current and future generations can experience healthy aquatic ecosystems in the National Park System. WRD provides assistance, expertise, and guidance for aquatic ecosystem stewardship. WRD provides its services directly to parks through a broad range of programs in the areas of fisheries, natural resource condition assessments, information management, hydrology, planning, ocean & coastal resources, wetlands, water quality, and water rights.
