Water Rights Decision 1641 (D-1641)

This decision is part of the SWRCB’s implementation of the 1995 Bay-Delta Plan. Many of the objectives in the 1995 Bay-Delta Plan are best implemented by making changes in the flow of water or in the operation of facilities that move water. Accordingly, this decision amends certain water rights by assigning responsibilities to the persons or entities holding those rights to help meet the objectives.
