I like how clearly structured it is. Each paragrph has a definitive idea, and they flow together very well.
I like that this is centred around a river, and that you use a lot of historical context to sho how the river has changed--but more than that, how the world around the river has changed.
I think you lean a little too heavily on metaphors at times--for example, you never say that the river floods, just that it cries. It's okay to be explicit sometimes! That said, your choice of imagery gives texture to the piece and helps us to understand where you're coming from as you write. Just be careful with your images--if you use fewer of them, they will be more powerful.
You have such a strong connection to this place, and that's so wonderful to read. Just keep exploring in specifics and it should be good :)
