We completed the Hike on August 4th. We were prepared with Plastic knee high shoe covers, because some of us didn't have tested water proof shoes. But we didn't use the Shoe covers and were all fine despite having to cross the streams. Stream crossings and sometime water on trails are well prepared with Logs and Stones - that keep you dry. But hiking poles are must in all these and other situations to help you balance while crossing streams. Hope this helps...
