Blackwater is a wonderful fish, but I have not fished it in years. If I remember correctly there is some access on the way upper portion outside of Quensel, I also remember in the past, it didnít open until late in the summer, after July 4th?. Not sure if this is still the case or not.
If you do decide to float, be very careful, as there is a canyon about 2/3rds of the way down, where the entire river flows through a small rock slot... you have to unload the raft, flip the raft on itís side and then push it through the slot, and reload on the other side. To this day, itís one of the damndest things I have ever seen. Obviously, this all needs to be scouted prior to running it.
