Due to the many dams along the Mokelumne River, salmon runs that used to cross through to the present location of the Pardee Reservoir are stopped short in lower sections of the river. In the Fall of 2014, the fifth largest
Chinook salmon count recorded in the past 74 years took place, with over 12,118 salmon. Below the dam lies a hatchery that is the result of a joint project with EBMUD and
California Department of Fish and Wildlife. 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. ==See also==
