The National Park Service states in its publication “Currents” that the Buffalo National River is viewed as a Class I river, which is generally accepted as the least difficult river rating. However, our section can move into the Class II rating in times of high water. We regularly update our Buffalo River Level Report during canoe season, as well as other times of the year when the river level comes up high enough for floating. You can check this report for a current airspace reading at Ponca and an indication of the skill level required.
