California is so beaver challenged. We need beaver summits every day. Whenever I come across a very stupid article about beavers I play a little game with myself. Where is it from? What region is so ignorant about beavers and hasn’t done the slimmest part of their homework?

This morning the answer was Sacramento.

Restoration brings salmon, people back to Clear Creek

Clear Creek has been transformed multiple times in the past two centuries, but the transformation of the past few decades was designed to last. Ravaged first by gold-seekers and then by gravel-miners, the Sacramento River tributary is today a haven for fish and people alike.

“You get to see big male salmon chasing each other away from females and see females digging redds, or nests. It’s exciting,” said U.S. Fish and Wildlife Service biologist Charlie Chamberlain. “It’s something a lot of people would not expect to see in California except on National Geographic.”

Thirty years ago, it wasn’t something you’d see in Clear Creek either. There was little water flowing, and Saeltzer Dam closed off more than 11 miles of potential habitat for sensitive species like Central Valley steelhead and spring-run Chinook salmon.

The Bureau of Land Management, however, acquired most of the Lower Clear Creek channel bottom in a series of deals in the 1990s. At the time, the creek was mainly known as an out-of-the-way place for illegal trash dumping and suspicious activity.

Well that’s nice. They fixed a stream for salmon. There’s plenty of good reasons to do that. And I’m sure other species benefit too.

Restoration began by increasing water flows through Reclamation’s Whiskeytown Dam, then removing the privately-owned Saeltzer Dam. Those steps brought fish to Clear Creek in the thousands, but the stream was nothing like its former self.

“Miners basically dug a ditch here along the valley and diverted the creek into it so they would have room for gravel extraction,” Chamberlain said of one part of the restoration area. “They took a creek that used to have this dynamism to it and serve a lot of ecological functions, then dumped it into a little chute where it had very little ecological function and no dynamism.”

“If you change the shape of the creek so it spreads out and trickles into the floodplain or side channels, you get extra-slow areas where you’ve wet new surfaces, and those floodplains generate a lot of fish food and grow vegetation,” Chamberlain said. “You get a food-based explosion.”

Workers have placed downed trees and more than 180,000 tons of gravel in Clear Creek since the 1990s to help create habitat. Salmon spawning habitat was the original focus, but the work has created diverse conditions that benefit fish in multiple life stages. The latest phase focused on juvenile salmon, but will also provide homes for beavers, song sparrows and pond turtles.

You know how it is. When you get a few BLM workers to lay woody debris in streams they make homes for salmon which also makes home to beavers.  ARGGGGGGGGGGGGGGGGGGGGG!!! The stupid! It burns us!!!!

Of course when the beavers themselves try to install woody debris and fan out the stream with their own dams they are considered a nuisance and killed. Why do you ask?

“For juvenile fish, woody debris provides refuges from predators and spots to hold and wait for food to float, swim or fly by,” said Matt Brown, who managed the Fish and Wildlife Service’s program on Clear Creek from 1995-2017. “There will also be areas for adult fish to hang out and rest before they spawn and other areas with good spawning habitat.”

Unless beavers put it there. And then its trash.
