do you know where water flows upward

This can somehow applies to "hot Springs" water comes from the earth and goes upward from kind of hot giant fountains :)

I can't say that i know the answer but I would like to tell you about a place in Canada, Saint John In Saint John when the tide comes into the Saint John Harbour it is so powerful it put the river into reverse and causes a big pile-up of water. They refer to this as the Reversing Falls and the water actually goes backward back up the river. Twice a day.

No i dont know and i dont think it flows upwards any where.

I don't know if I am right or not. but I'll say Montana's "Old faithful" at Yellowstone National Park.
