Between 1992 and 1997 some uplift occured due to recovering ground-water levels.

In Santa Clara Valley, California, subsidence has been arrested by importation of surface water and careful management of the aquifer system. The interferogram indicates no change for most of the southwestern Santa Clara Valley and land-surface uplift of up to about 24mm in the northern and eastern parts of the valley. This uplift is correlated to the recovery of ground-water levels that has been occurring for several years as a result of reduced pumpage and increased recharge.
