​Summer low flow conditions may create sandbars within the creek channel downstream from the George Johnston access point. Paddlers may have to exit their watercrafts to pull over the sand bars. The location of the Willow Creek channel may shift from year to year. Paddlers must have navigation experience as ‘dead end creeks’ will be created, requiring paddlers to backtrack to the proper channel. Moderate to high winds will make travel through the open marsh difficult.      Paddlers may have to exit their watercrafts to get through mud flats
