One of the largest salmon hatcheries in Alaska was forced to destroy thousands of fish after a landslide Wednesday damaged a pipeline that supplies its water.

The Macaulay Salmon Hatchery in Juneau is run by Douglas Island Pink and Chum Inc., known locally as DIPAC, reported the local news site KTOO.

Hatchery staff destroyed all the young chinook salmon and rainbow trout that would have been released next spring, according to the news site.
