Back in February when I fished in Larry Scott DB.
We went from Dimmel to Confluence on day 1.
I remember that log on the right channel.
The water flow was just high enough to flow over the log but the log was clearly visible.
Larry floated his boat right over the log and he did that very smoothly.
Not that I would want to attempt it.
I would assume that log is still there on the right channel.
Be very careful on the lower Sol Duc.
