River levels continue to fall along the Missouri river which will allow for trail cleanup to occur. Expect rougher trail conditions in St. Charles and Rocheport. Additionally, all parts of the trail were under threat of flash flooding. Reports of rock near Pilot grove have come in as well as washouts near St. Charles.
