Why? Shut it down sure but why produce cutthroat? That hatchery is designed to simply incubate eggs with no or very minimal rearing. Relatively very little water is used/permitted for diversion. Rearing of fish to a large release size will require lots more water, lots more infrastructure, and lots more operating cost.

If the lake is so good for cutthroat, manage for it? Why not be satisfied with what the system can produce?
