Tribes in the Pacific Northwest have faced persistent obstacles to their exercise of treaty fishing rights, most prominently illegal regulation of off-reservation fishing by state governments. As salmon decline, a new frontier is emerging for treaty right violations: environmental degradation. A recent court victory ruled that a series of culverts owned and operated by the state of Washington violated tribal treaty rights to fish for salmonids at their “usual and accustomed” places.

There has been an influx of “climate superfund” bills introduced and adopted in state legislatures across the country. Modeled after the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), these laws are designed to recover costs from large emitters of greenhouse gases (GHGs) to pay for climate adaptation infrastructure.
