One of the interesting aspects of steelhead management is that it is 50:50 sharing in each river. In salmon, the NI side takes loads of fish (the desoreable Chinook and coho) in the ocean so getting less in the river makes legal sense. But for steelhead that fioesn't hold. So, if there are fish for one side, there must be fish for both. Unless WDFW agrees to not catch them so the Tribes can (non-selectively).
