designated by this Act the provisions of the Wilderness Act shall not be construed to prevent the installation and maintenance of hydrologic, meteorologic, climatological, or telecommunications facilities, or any combination of the foregoing, or limited motorized access to such facilities when nonmotorized access means are not reasonably available or when time is of the essence, subject to such conditions as the Secretary of Agriculture and the Secretary of the Interior deem desirable, where such facilities or access are essential to flood warning, flood control, and water reservoir operation purposes. SEC. 306.
