. There, about a fourth of the returning salmon are collected and harvested for egg production. Along with raising the salmon, scientists work to manipulate river flow to encourage more salmon to return. During times of low water level, the fish are at risk of being drawn into water pumps that lead towards the south past the delta. To avoid this, scientists truck the baby salmon from the hatchery to Sherman Island in the delta. The goal of the hatchery is that the baby salmon will imprint to the water in the Mokelumne River and return when it is time for them to mate.
