For over a decade now, the Nisqually Tribe has lead a ground breaking effort to restore endangered chinook on the Nisqually River. Those efforts are the centerpiece of two episodes of Carl Safina’s Saving the Ocean series. Both episodes will air tomorrow night at 7 p.m. on KTCS in Seattle.

You can also watch both episodes online right now if you don’t want to wait.
