If you were thinking of taking Monday off to float the Buffalo, forget it. The river has risen above its banks in the four places (marked on the map with red triangles and blue balloon), and swift water and floating debris present a danger to even the most experienced canoeists, the National Park Service says. Various news reports say the Tyler Bend campground is completely under water; the river should crest there this afternoon at 47 to 50 feet, according to KFSM News, which has images of flooding on its website.
