Yes, WDFW likely has leverage to do things like close hatcheries that don't benefit the State's citizens. I suspect there are two reasons why they won't ever exercise any such potential authority:

1. WDFW doesn't want to close hatcheries, for a variety of organizational reasons.

2. The non-tribal, commercial lobby doesn't want hatcheries closed, and they contribute to the real deciders' campaigns to protect that interest. Not all "citizens" are equal in the eyes of the body that approves budgets; those who bring the most money get the best representation. Not much different than any public issue in that respect....
