History
The hatchery was built in 1963 to offset the loss of fish spawning habitat due to the construction of Camanche Dam.
From 1987 to 1992, there was a drought in the area. Low flows and a series of fish kills reduced the Mokelumne River steelhead run during the 1980s.
In response, EBMUD implemented several programs to improve water quality, flow regimes, and physical habitat in the lower Mokelumne River. The hatchery was remodeled in July 2002, enlarging the rearing space to promote fish health and fish survival rates while also making hatchery operations more efficient.
Since then, the Lower Mokelumme River Fishery Resource has thrived, as evidenced by counts of fall-run Chinook salmon escapement or returning salmon. Returning salmon increased by 3,028 from 1998 to 2003.

Famous quotes containing the word history:
“Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?”
—Alexander Herzen (1812–1870)
“Books of natural history aim commonly to be hasty schedules, or inventories of God’s property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.”
—Henry David Thoreau (1817–1862)
“Every library should try to be complete on something, if it were only the history of pinheads.”
—Oliver Wendell Holmes, Sr. (1809–1894)
