I didn’t manage any pictures to prove this (due to failing light) but I stopped at Black Rocks this afternoon to see if I could see any salmon at the falls and hey presto, I saw at least 2 different fish in the 5 minutes I was there. I say at least 2, but actually I saw 4 fish at the falls but 3 of the four could have been the same fish. The other was considerably bigger.
I will try an get photos in the next few days if I can. Watch this space.
