Water Resources Development Act

What is the Water Resources Development Act?

The Water Resources Development Act is a comprehensive legislative package that provides for the conservation and development of water and related resources. It authorizes the Secretary of the Army, through the Assistant Secretary of the Army for Civil Works, to conduct studies, construct projects and research activities that can lead to the improvement of rivers and harbors of the United States.

WRDA is strictly authorizing legislation; it does not include funding. The funding of WRDA-authorized studies and projects is provided separately through the annual Energy and Water Development appropriations process and, at times, through supplemental appropriations.
