How is a watershed affected by humans?
Building dams and rerouting rivers are two examples of ways humans directly impact water in watersheds. Humans also use water as a resource, drawing from watersheds for our drinking water. This does not have to be a negative impact, as water usage can be monitored so that it is sustainable.
