This had a very depressed and frightening feel to it, which I happen to love
. Your descriptions are very vivid, every line simply adding onto the luscious imagery of the water. The entire poem seems to have hidden depth and is an extended metaphor for water/life. I like that you kept it simple, using only one element, but it still made me think about each line. It has its surreal aspects and then more natural concrete ones, like the hills. I can't really think of much for you to work on except for repetition. In a piece this small repeated words stand out. one place is "Of the once gentle circles" because gentle is such a strong word at the beginning and end, I'd replace this random use of it with languid or some other such word. The second word is "until" which is used twice in a row. It only sticks out because it is not seen as a pattern elsewhere. Its up to you if you want to change it but I think it might be smoother if you took one out.
