Rec. 2.c.1: The DoD OIG recommended that the Under Secretary of Defense for Acquisition and Sustainment review and update DoD Directive 4705.01E to update the Joint Water Resources Management Action Group Charter within DoD Directive 4705.01E to clarify the roles and responsibilities of the Joint Water Resources Management Action Group. Specifically, the updates should identify the specific DoD Components that should attend the Joint Water Resources Management Action Group and instruct those Components to issue guidance designating an office of primary responsibility for attending and communicate those designations to the Executive Agent.
