As to defunding WDFW I think there are couple things to do but they would be highly political.

The first is have the Leg create a new FW fishing license. Applies ONLY to non-salmon (including steelhead) in FW. The kicker is that funds from the license could only be used for hatchery production,stocking , and management of the species. Could not be used for habitat (that is a state wide duty fundable by all taxpayers, administrative oversight, and enforcement. May have missed something, but Salmo can add it.

Although much more risky I think we should elect the Commission. Four from Eastside. Four from Westside. They would be elected by east or west voters. Chair elected statewide. A requirement of qualifying for election, perhaps except Chair, is that they have held WDFW-issued annual licenses in five of the past 10 years and must hold one annually when in office. That would get the Gubbernor on Leg out of the equation.
