Superintendent Todd Brindle at Glen Canyon National Recreation Area announced that due to low lake levels, it is not recommended that boaters use the Castle Rock Cut for safety reasons.

In 2008, the National Park Service completed an excavation of Castle Rock Cut that lowered the depth to approximately 3,610 feet in elevation. With water levels currently at 3,614 feet, the cut is no longer a safe passageway for larger vessels. Park staff placed buoys on both sides of the cut that warn boaters of low lake levels and to enter at their own risk. Boaters will now need to travel around Antelope Island to reach uplake destinations such as Padre Bay and Rainbow Bridge. The park will notify the public when the lake elevation is high enough to allow for safe passage through Castle Rock Cut.
