I was on Dardanelle last Saturday and the river was rolling.
Keep in mind that it being wider than up around Fort Smith and Ozark, the same water and trash still goes through Dardanelle. Personal opinion is if you stay down towards Russelville you won't see as much big water as you would up river, but still potentially dangerous.
It was flowing 180k yesterday and 170k today.
Regardless, be careful and keep a watchful eye.
