UPDATE: As of June 17, the hatchery is once again open.

The California Department of Fish and Wildlife (CDFW) has suspended all fish planting from the Hot Creek Trout Hatchery in Mono County as a bacterial outbreak has been detected at the facility.

“Unfortunately, the timing couldn’t be worse with the holiday weekend coming up, Mule Days taking place in Bishop and a lot of people coming to fish the eastern Sierra this time of year,” said Jay Rowan, Acting Fisheries Branch Chief for CDFW. “We don’t yet know the extent of the outbreak at Hot Creek Hatchery, but we do have the advantage of some additional tools in our toolbox now versus a year ago, including recently developed vaccines that we started rolling out to fish at the three previously infected hatcheries earlier this month.”

 The three other CDFW trout hatcheries in Southern California and the eastern Sierra are the Mojave River Hatchery, Black Rock Trout Hatchery and Fish Springs Trout Hatchery. That outbreak ultimately forced the euthanization of 3.2 million trout at those hatcheries.
