The amount of poetry in a picture is so difficult to materialize. Moreover, the perception of the poetic aspect is very personal and subjective. And finally, poetry is not to be confound with romanticism or melancholy.
Isn't the decline of the tree and the plants, associated to the autumnal colours and the stones contrasting with the dark green water a poem? My mood was very positive that day, the view of this marvellous nature made me happy - but also thoughtful and meditative: it showed me that I also have reached the autumn of my life, and I was balanced between happiness and sadness.
Victor Hugo said once: Melancholy is the happiness of being sad.
Poetry... where are you?
