Question:
Why has the amount of water in the Owens River dropped to very low levels in the 20th century from natural conditions that had lots of discharge? Group of answer choices California has been in a drought since the mid-20th century. Los Angeles built canals to divert water before reaching the Owens River. This part of the country depends on groundwater, and groundwater levels have steadily dropped over time from overuse. The water sinks into the ground, because the river bottom is so porous.
