Spraying was unexpected but it was unique and I liked that.

Current's power should have an apostrophe.

Other than that nice Tanka.

Gushing and surging,

*Very good action verbs. I love the imagery, it's very simple but also beautiful. Keep it up hun. Nik*

"The flow of water,"

I loved that first line, it drew me in and was uniquely worded.

"Flowing down from place to place."

The repeat of "flow" kind of threw me off, maybe replace with "Racing" or something like that?

"Gushing and surging,"

Great action verbs here, the imagery was so strong and powerful.

"Spraying on rocks and side beds;"

Wow, this is beautiful, I'm impressed!

"Showing the current's power."

Indeed they do, a lovely tanka. Keep writing, always and forever..
