A big change this year over two years ago was the tremendous amount of trees that fell into the river (due to the fierce storm we had over the winter). On a couple of occasions the trees blocked the passage of our canoes and we had to work around them.
I might add that if you want to go on this route, make sure you have an experienced back person because the trees have created some fun twists and challenges for small craft. Trip took 5 hours.
We saw some osprey, ducks and even one bald eagle. Otherwise no other mammals (perhaps we were too loud).
Good April/ May trip when levels are higher.
