The salmon are already back, for the first time in 102 years!

it must have been a nice life for the Native Americans before the pale faces showed up and ruined the rivers- I've read that in a few days they could catch enough salmon and other fish to feed themselves for months

Oh man the pre-dams Elwha salmon were/are legendary. Simply opening up the entire Elwha watershed to salmon spawning again in and of itself is a relief. Represents such a huge advancement in protecting all five species of native Pacific salmon from eventual extinction. I wish my salmon ecology professor from grad school was still alive to see this.

For others consuming enough salmon to last a while, check out the following live cam of the McNeil River, that feeds into the Cook Inlet, Alaska:

Because it is a live cam, view it during daylight hours, four hours earlier here in Alaska Daylight Savings time. While it's nearly midnight your time when I'm typing this, it's nearly 8PM our time. It's late in the season, so you may have to check it out more than once...

A video of chinook salmon in the river. It looks like it's roughly the old site of the Glines canyon dam:

Some sockeye salmon have also been found in the river:
PORT ANGELES — Sockeye are the latest salmon species to reappear in the newly free-flowing Elwha River.

Scientists working with the Coastal Watershed Institute found several juvenile sockeye this week in the Elwha’s mouth. It’s the first time sockeye have been spotted in the Elwha’s nearshore zone since monthly sampling began more than eight years ago.

Chinook and coho salmon and steelhead trout have been spotted in the river since the dam removal project was completed last year.

“There’s lots of discussion and hope for what will happen to these stocks after dam removal,” said Anne Shaffer, director of the Port Angeles-based institute. The recent trend has been to first see one or a handful of a salmon species followed by a sudden abundance. Candlefish, a threatened species that serves as an important food source for salmon and other marine animals, also recently reappeared in the Elwha after a decadeslong absence.

“We hope the Elwha nearshore trend … will hold for sockeye, too,” Shaffer said.

While the appearance of the sockeye is a good sign, University of Washington salmon ecologist Tom Quinn cautioned that the fish hasn’t yet joined other salmon species in venturing beyond the dam sites.

“This might be a harbinger of a population that’s growing, and that would be very cool if it was, but we have to be cautious,” he said. A stronger indication of the sockeye’s return would be to find adult fish returning and spawning in the river.

Sockeye never really left the Elwha after the Elwha and Glines Canyon dams were erected. Scientists believe the dams might have trapped some sockeye in Lake Sutherland, which drains into the Elwha via Indian Creek. Known for their adaptability, the sockeye transformed into “kokanee” and shifted their diet and reproductive behavior to a landlocked freshwater environment. A few of kokanee are said to have slipped past the dam each year but none was documented in or near the river’s mouth until last week.

It’s unclear what’s happening with the Sutherland kokanee, but Quinn said studies of other kokanee populations have shown them surviving the transition back to a life at sea.

Seattle Times: More Elwha fish find way to dam-free upper watershed

By Lynda V. Mapes, Seattle Times environment reporter
October 17, 2016

More sockeye, chinook and bull trout have made it above the former Glines Canyon dam site so far this spawning season than documented in any year since the unprecedented dam-removal project was completed on the Elwha River.

The fish returns this season are an encouraging sign that blasting work in the river last summer to improve passage after initial dam removal has made a difference. Numbers aren’t yet final, but so far snorkel surveys and radio telemetry used by scientists to track and monitor fish throughout the Elwha show that from the end of July through the end of September, about 70 chinook salmon made it above the former Glines Canyon dam site.
