First, train in the preliminaries

In one area west of Tipton,
the ground has sunk more than seven feet since 2015.

As large amounts of groundwater are extracted,
layers of sediment and clay
collapse give way
and cause the land surface to subside.

About 3.5 feet of land subsidence
has been measured
along parts of the Friant-Kern Canal —
built by the federal government in the 1940s
to transport water
for more than 250,000 people.

The plans don't adequately limit account for
what is being taken.

Current pumping depletes, on average,
at least as much water each year
as the combined usage
of half a million homes —

domestic wells at risk
of going dry.

The canal sinks toward the level of what it carries.
