Boaters are advised that the Wahweap Main Ramp will be closed to motorized vessels beginning Monday, due to low water conditions. Officials say vessels up to 36 feet in length and 8 feet 6 inches wide may utilize the Wahweap Auxiliary Ramp from 6-am until 7:30-pm, daily. National Park Service staff have already begun to direct boaters to the Wahweap Auxiliary Ramp. Non-motorized vessels may continue to launch and retrieve from Wahweap Main Ramp. Wahweap Swim Beach and the associated parking area will also close Monday, due to construction activities at the Stateline Auxiliary Ramp. Lone Rock Beach and other undeveloped shorelines remain available for swimming. Visitors are reminded that swimming is prohibited at marinas and boat ramps.
