The fact that State shows little or no desire to challenge the Tribes is the result of decisions made by State leadership, above WDFW's pay grade.

The State is, I believe, afraid of what might happen if the Tribes aggressively asserted Habitat Issues un Boldt II (see Culvert Decision). The whole economy of the state would be at risk.
