Yep, these bores can be really cool, if you catch one of those documentaries. There are also bores in Canada, England, France, etc.
As someone mentioned one year a lot of spectators got too close and got drowned at the one in China.
The fishermen have to take their boats out on every high tide and "surf" the bore in the middle of the river so they don't get smashed to smithereens in dock.
I would not expect this on a river. Yowwwza
