In addition to the dry reaches, the higher discharge in the San Joaquin will help restore a total of of river, figuring in stretches with low or polluted flows. It is also hoped that the water will help dilute contaminants in the river caused by pesticides and fertilizers that are applied to the surrounding farmland. In turn, the boost in flow could assist restoration efforts and help flush out saline water in the Sacramento-San Joaquin Delta, where water is pumped into state aqueducts which provide water supplies to two-thirds of Californians.
