Land Subsidence Along the Delta-Mendota Canal

2015 (approx.)

Detailed Description

Reduced surface-water availability (associated with droughts) during 1976-77, 1986-92, 2007-09, and 2012-current caused groundwater-pumping increases, water-level declines to near or beyond historic lows, and renewed aquifer compaction. The resulting land subsidence has canal buckling and reduced flow capacity of the Delta-Mendota Canal (pictured), the California Aqueduct, the Eastside Bypass, and other structures that transport floodwater or deliver irrigation water.
