Here is what I got. I derived the numbers based upon the objects going over the falls.
1. Lantern marked with an 7
2. Black Bottle - 1
3. Black Bottle - 1
4. Black Bottle - 1
5. Bouy with 2 Red Marks
6. Grey Bottle marked with a 6
7. Latern marked with an 8
8. Black Bottle -1
7111 2681
That is the final answer I submitted...It is probably wrong
