IMPORTANT HIGH WATERCONSIDERATIONS:

Floaters, fishermen and swimmers exercise caution this weekend.Wear life preservers, protective footwear and other suitable clothing.Never swim or boat alone. Stay within sight of companions.Boaters inform family members or others what stream reach you’re floating and when you plan to return from your trip.Floaters beware, a number of flood events have occurred since the last float season. Fallen trees and debris may have accumulated in turns and runs that may pose navigational hazards.If in doubt about the stream reach to be traveled, stop and get out on land to scout a safe pathway to use to float through, around meanders and other areas where debris and

fallentrees present strainers that let water pass through yet will trap and hold aboat/swimmer. In areas with swift water, portage your boat around navigationalhazards.

Please adhere to COVID-19 Guidance from Oklahoma State Department of Health and CDC when enjoying Oklahoma Scenic Rivers Areas.
