The hatcherey is legislativly mandated as mitigation for the Landsburg Diversion. Around 1990. originally, it was supposed to have bneen a spawning channel. IHNV rendered that idea moot. From there, the hatchery was designed.

The original, temporary hatchery was supposed to support a whole series of studies designed to figure out what was going on in the lake. I don't think they all got completed.
