Hundreds of steelhead are showing at the Mokelumne River Fish Hatchery this season.
Large numbers of fall-run Chinook salmon have returned to the Mokelumne River in Clements this fall despite challenging salmon fishing on the Mokelumne and adjacent sloughs this season.
A total of over 12,658 salmon have gone over Woodbridge Dam in Lodi on the Mokelumne as of December 10, according to Will Smith, manager of the CDFW’s Mokelumne River Fish Hatchery.
“We’re seeing a good, above normal season, although anglers have reported slow fishing in the river,” Smith said. “We will probably see just over 13,000 fish this fall.”
The hatchery trapped 2,168 adult males and 3,324 adult females, along with 2,063 jacks and 560 jills.
The hatchery took 1.4 million eggs on the best day this year alone. The hatchery has taken 7.9 million eggs to date. “We may take another 100,000 eggs next week, but we’re pretty much done,” said Smith.
A record number of fall-run Chinook salmon, 19,954, went over Woodbridge Dam in the fall of 2017, the highest number since 1940. The 2018 fall salmon returns were also impressive, with a total return of 17,474 fish.
These record runs have contributed greatly to the ocean recreational and commercial fishery over the past couple of years. The Mokelumne, a relatively small river, provided 33 percent of the Central Valley fall Chinooks caught in the recreational fishery and 43 percent of the commercial fishery in 2018, according to the Pacific Fishery Management Council in February 2018.
Hatchery staff plan to raise and release 6.8 million smolts into the San Joaquin River and other sites in the spring of 2020.
