The floods following the series of storms spawned by Hurricanes Frances and Ivan in September 2004 have changed the character of the river. The rains lasted days and flooding was severe. Portions of the towns of Canton and Clyde were completely underwater, and there was significant damage to a large portion of both towns. Farther upstream the water levels reached unprecedented levels. Part of Interstate 40 collapsed into the river gorge because of the force of the floodwaters. This began when trees on the hill beside the highway fell in the river, followed by the soil the trees had held in place. The shoulder gave way, and a guardrail ended up just hanging.
