Environmental Impacts

Ground water levels have been declining, much like the river’s surface flows that once flowed into the Gulf of California. Some of the declines may be due to drought, some to overpumping and some to the loss of agricultural runoff as farmers become more efficient. Researchers warn that a groundwater “depletion zone,” where levels have dropped too far to support riparian vegetation, is extending both upriver and downriver from an area near the border. Such zones are created when the groundwater pumped out exceeds what is replaced,...
