Any body of water in a city collects dirt over time. When the water is gone cleaning becomes possible.

- CydeWeys 9y agoDredging is a common maintenance activity on canals, and is easier to do with the water present (since you can use ships) than when it is absent. It's certainly easier to pop down with a trash bag and pick up litter when the water is absent, but for dredging the dirt, you need the water to come back. There's no good way to move it around without being able to float it off in a boat on the water.
