Prior to the mid 20th century, the Colorado River flowed continuously from the Rocky Mountains to the Gulf of California. Since this time, several major projects have taken water away from the river's natural course One of these projects has been the
Colorado River Aqueduct
, which takes water from the Colorado river and transports it to the Los Angeles area for drinking water
Today, dunng many times of year, the Colorado River no longer reaches the Gulf of California
The dam pictured
below takes water from the Colorado River so it can be transported along the aqueduct On the night, a dried. up portion of the river in Baja California is shown
This example illustrates that
OA. human activities can vastly change how water flows along the Earth's surface.
ОВ.
humans are helpless to change the way that water flows along the Earth's surface.
