Did they just show up to look at the mess or did they clean out what was there? With the water up, more stuff will probably float down and you don’t need more piled up with what was there.
This is the only mess I can see from the deck.
Here I'm standing on the bridge that goes from my cul-de-sac over the creek to the school yard. My jungle to the left, city propery to the right, with a dam forming in the middle.
