PBS Documentary on Salmon

Salmon: Running the Gauntlet, aired on PBS's Nature series a couple of weeks ago. It's a look at salmon troubles in the Columbia River Basin and the efforts to stop their steep decline. Nicely shot, with some terrific underwater footage, it touches on some of the politics of salmon, but not in great depth.

While many of the issues are similar to the ongoing problems in the Delta, there are also many key differences. In the Columbia Basin, it's more of a fight over dams impeding the salmon's journey upriver to their spawning grounds, while in the Delta it's a fight over adequate water flows, and not just for salmon.
