Congress expressly reserves to the United States the minimum amount of water required to carry out the purposes for which the national monument, the conservation area, and the wilderness areas are designated under this subchapter. The priority date of such reserved rights shall be December 31, 1987.
Nothing in this section shall affect any existing valid or vested water right, or applications for water rights which are pending as of December 31, 1987, and which are subsequently granted: Provided, That nothing in this subsection shall be construed to require the National Park Service to allow the drilling of ground water wells within the boundaries of the national monument.
Nothing in this section shall be construed as establishing a precedent with regard to any future designations, nor shall it affect the interpretation of any other Act or any designation made pursuant thereto.
