What to do
If you are in the Paria River slot canyon, get out now. The National Weather Service says flood waters will flow down the Paria River and reach the Colorado River at Lees Ferry between 5 PM and 8 PM tonight.
Stay away from the Paria River and the Colorado River near Lees Ferry, including the Lees Ferry Camp Site. Move to higher ground and keep clear of washes and creeks.
Never drive around barricades or into flooded roads. Just 6 inches of moving water can knock you down, and 1 foot of moving water can sweep a vehicle away.
