(iii) Certain areas designated in table 1 to paragraph (f)(3)(ii) will close and open to off-road motor vehicle use pursuant to the provisions in this paragraph (f)(3)(iii).

(A) The superintendent will identify lake elevation levels for each of the following areas designated in table 1 to paragraph (f)(3)(ii): Lone Rock Beach, Blue Notch, Bullfrog North, Bullfrog South, Crosby Canyon, Dirty Devil, Farley Canyon, Hite Boat Ramp, Red Canyon, Stanton Creek, and White Canyon.

(B) The superintendent will use hydrologic data from the United States Geological Survey and the Bureau of Reclamation to identify the lake elevation levels, which would be subject to change based upon public health and safety, natural and cultural resource protection, and other management activities and objectives. The superintendent will notify the public of the lake elevation levels by publishing them on the website of the recreation area and in the superintendent's compendium (or written compilation) of discretionary actions referred to in 36 CFR 1.7(b).

(C) If the lake elevation drops below the identified level for a designated area and remains below the identified level for seven consecutive days, the superintendent will close the designated area to off-road motor vehicle use. If the lake elevation increases above the identified level for a designated area and remains above the identified level for seven consecutive days, the superintendent will open the designated area to off-road motor vehicle use. The superintendent will notify the public that a designated area has been closed or opened to off-road motor vehicle use within 14 days after the expiration of the seven-day waiting period, by publishing a notice of the management action on the website of the recreation area and in the superintendent's compendium.

(D) The National Park Service will install signs at each designated area notifying the public that it is opened or closed to off-road motor vehicle use. When a designated area is closed because lake elevations have dropped, the superintendent will consider additional steps to prevent off-road motor vehicle use in the area, such as the installation of gates. Motor vehicle use on a GMP road may continue within a closed designated area at the discretion of the superintendent, and subject to the rules for operating a motor vehicle on such roads in this paragraph (f).

(iv) Off-road motor vehicle use in any of the areas designated in table 1 to paragraph (f)(3)(ii), except for Lone Rock Beach, Lone Rock Beach Play Area and Ferry Swale, must be for the purpose of traveling from a GMP road to the shoreline, and back.
