OAKLAND – The East Bay Municipal Utility District (EBMUD) reports more than 10,500 Chinook salmon returned to the Mokelumne River from the Pacific Ocean to spawn during the 2025 fall run. These returns represent a healthy count for natural spawning in the river and allowed EBMUD’s fish hatchery to reach its goal of collecting and fertilizing 7.5 million salmon eggs in coordination with the California Department of Fish and Wildlife (CDFW).
Though the Mokelumne contributes only about 3 percent of the freshwater flow into the Sacramento-San Joaquin Delta, its salmon population has made up as much as 50 percent of the commercial catch off the California coast.
