An affect of fresh water
As you should know, water runs downhill, going to the water source, which also collects sediments from the ground, which is carried to the water source making the clean water dirty with sediments from the ground.
Where do we get our water from?
We obviously get our water from aquifers, aqueducts, reservoirs, etc.
In California, there is about 1 aquifer, which is called California Central Valley Aquifer System.
Also there are about 64 aquifers in North America!
There is also only one aqueducts called Governor Edmund G. Brown California Aqueduct.
