Norm Dicks inducted into Wild Salmon Hall of Fame

From childhood, U.S. Rep. Norm Dicks was destined to become an advocate for salmon and ultimately a champion for the entire Puget Sound ecosystem, according to recent comments from his family and friends.

Most people know that Norm — whose home lies in southern Hood Canal — will leave office at the end of this year. Recognizing his efforts on behalf of salmon, the Pacific Northwest Salmon Center recently named him to its “Wild Salmon Hall of Fame.”

Neil Werner, executive director of the salmon center, said Norm embodies all the criteria for hall of fame inductees, such as a passion to restore wild salmon, a willingness to share knowledge and much success in making things happen. Listing the criteria, he said, is like describing Norm Dicks himself.

I won’t list all the accomplishments that Neil cited during an induction ceremony two weeks ago, but they included Norm’s leadership in obtaining congressional funding for a variety of programs to restore salmon in Puget Sound, to heal the Puget Sound watershed (including federal lands) and to increase our understanding of how the ecosystem works.

As a result, salmon have regained access to 900 miles of stream habitat, including the nearly pristine watershed above two dams on the Elwha River.

“We will see the benefits of what he has done for an awfully long time, if not in perpetuity,” Neil said.

Blasts punctuate anniversary of Elwha Dam project

The folks at Olympic National Park who keep us informed about the Elwha River Ecosystem Restoration Project could not have described it better: “It has been an explosive week at Glines Canyon Dam,” they said in their “Dam Removal Blog.”

The “salmon window,” designed to protect migrating fish, has now closed, allowing work in the river to begin again. This week, four big blasts blew out large sections of the dam on Saturday, Monday, Tuesday and Wednesday, as the reservoir level dropped from 489 to 476 feet, according to the blog. Click on the image to start the video of the blasting.

After an upcoming blast on Sunday, a 14-day waiting period will begin to allow the river to erode laterally.

The remote cameras at both the Elwha and Glines Canyon dams are useful for observing environmental and structural changes in the areas around the two dams. An unexpected use came into play Thursday, when an average person looking at the Elwha Dam webcam noticed a fire burning at the edge of the picture.

Firefighters from Clallam County, the Washington Department of Natural Resources and Olympic National Park were able to extinguish the blaze before it could burn more than half an acre. The cause of the fire is under investigation. Read the news release about fire danger in the national park.

It’s worth noting that we have just passed the first anniversary of the start of dam removal. The Elwha Dam is gone and most site work is complete. Glines Canyon Dam is about 60 percent removed. And salmon have been observed swimming upstream of the Elwha Dam. Click on the image (lower right) to start the video, which shows what has happened over the past year.

Contrasts emerge at Glines Canyon Dam

The delta and shoreline above Glines Canyon Dam provide a stunning contrast to the surrounding forest in this photo take yesterday by Tom Roorda.

Work in the Elwha River stopped Aug. 1 for the “fish window,” which will halt all in-water work until Sept. 15. During this time, steps are being taken to reduce flows of sediment, which can harm migrating salmon. Salmon are being trapped downstream for transport into clearer waters above the dams.

As you can see, the reservoir level has come down at Glines as more of the delta is exposed and the river seeks multiple routes on its downstream course.

Tom Roorda, owner of Northwestern Territories, has taken aerial photos of the Elwha and Glines Canyon dams and their sediment plumes since the beginning of dam removal. Check out his website, Roorda Aerial, which contains a slideshow of some interesting and beautiful aerial photos.

As we have discussed, the lower Elwha Dam has been removed and the river is flowing at historical levels. Massive amounts of sediment are moving downstream and into the Strait of Juan de Fuca. The finer sediments that have reached the Strait so far tend to disperse rather than accumulate.

During the fish window, work crews at Glines are preparing to demolish the intake tower, which is no longer in the river. A blast at the base will drop the tower onto its side, allowing a jackhammer attached to an excavator to break up the concrete.

In July, six controlled blasts lowered Glines Canyon Dam by 24 feet to the current elevation of 490 feet. About 90 feet of the original 210-foot-tall dam remain, according to the “Dam Removal Blog,” written Olympic National Park staff.

The two final blasts on July 29 and 31 notched the dam the final six feet to elevation 490 feet. Videos of three of the blasts can be viewed below in these explosive shots provided by URS:

Amusing Monday: Old photos show wonder of water

“No matter how you spell it or how you pronounce it, H2O is a wonder: a beautifully simple, simply beautiful element that, when all is said and done, means nothing less than life.”

Thus begins the introduction to a collection of historical photographs titled “In Praise of Water,” which includes mostly amusing pictures from 1936 to 1968. The collection was put together by Life magazine in recognition of World Water Day last month, but I just stumbled on it last week. Please click on the link to take a look. (For the chemists among us, we’ll have to forgive the term “element,” because water is actually a compound.)

To bring the wonder of historical photos back home to Washington state, I pulled this fabulous photo of Eleanor Chittenden fishing on the Elwha River in 1907. It’s from a collection managed by the Washington State Historical Society.

Eleanor, 15 in this picture, was the daughter of famed engineer Hiram Chittenden, who worked for the U.S. Army Corps of Engineers in connection with the Port of Seattle. The photo, by Asahel Curtis, was taken during an expedition to the Olympic Peninsula with The Mountaineers. Eleanor was no doubt proud of her catch, a very nice steelhead. Of course, this was many years before a dam was built on the Elwha.

Bob Royer wrote a nice piece about “The Girl and the Fish” in the Cascadia Courier, a blog that relates history to present-day events.

Elwha Dam: Keeping an eye on sediment flows

Removal of the Elwha Dam and drawdown of Lake Aldwell behind it have gone faster than originally planned, and now the story of the Elwha River restoration becomes a story of erosion. Experts are watching the sediment movement very closely.

Taken today, this photo shows the sediment once impounded by the Elwha Dam but now free to move. The drawdown is on hold to allow the river to redistribute the sediment.

The Elwha Dam has been entirely removed down to the river bed (see photos below), and the river is now flowing in its original channel, where it will remain. The river is being held back mainly by a “check dam” of boulders. At the moment, the drawdown has been halted at 133 feet elevation for a scheduled two-week holding period.

Andy Ritchie, restoration project hydrologist with Olympic National Park, says the pause in drawdown will allow the river to snake around to redistribute the sediment more evenly across the valley. The final target elevation for the river bed is 100 feet.

Drawdown of Lake Mills, behind the upper Glines Canyon Dam, also is on hold at the moment. Even more sediment is trapped behind that dam. While project managers have largely lost control over the movement of sediment behind the lower dam, the upper dam remains intact enough to control migration of sediment from farther up the canyon.

As the weather improves this spring (or at least we can hope), it may be time for many of us to visit the former lake beds at the two dams. We can walk out onto the deltas and see the new vegetation starting to grow. Lake Aldwell’s delta can be reached from the old boat launch. For Lake Mills, take Whiskey Bend Road, which has been reopened, and you will come to Humes Ranch trailhead with access from there.

Elwha work resumes as structures disappear

Work resumed yesterday on the Elwha Dam site after biologists determined that the annual chum salmon migration had ended. The work originally was to be delayed until Jan. 1.

Work in and near the river stopped on Nov. 1 to protect fish runs from heavy sediment, as scheduled in a work plan adopted several years ago. Three work stoppages — known as fish windows — are planned each year.

Adult chum salmon were captured as they returned and were transferred to the fish hatchery operated by the Lower Elwha Klallam Tribe, according to a news release from Olympic National Park. Offspring of those chum will be released into the river in the spring.

It’s been awhile since I posted photos from the demolition site. As you can see from the pictures on this page, the change since mid-September is dramatic.

Most of the Elwha Dam powerhouse has been removed, and work is scheduled for completion at the end of this month, according to the park’s Dam Removal Blog. Materials from the old power plant are being recycled.

All the old power lines and poles associated with Elwha and Glines Canyon dams have been removed.

The 120-foot-tall surge tower was pushed over Thursday.

The river was diverted back into the right channel yesterday, as water levels behind the dam continue to go down.

Revegetation of the two reservoir areas started in November and continued into December with the planting of about 12,000 plants. Another 18,000 plants are planned for January and February.

If you’d like to watch the entire demolition of either dam to date, go to the Elwha River Restoration Project webcams and click on “Java” for any of the cameras. The fastest way to watch the entire time-lapse series is by putting the delay on 0.

Glines Canyon Dam shows off its new notches

“Deconstruction” of Glines Canyon Dam on the Elwha River appears to be progressing rapidly. A fourth notch in the dam was completed yesterday, and water is now pouring through all four of the gaps.

Alan Durning of Sightline Institute (blog) pieced together the video, at right, from still photos taken by a remote webcam at the dam. Check out the cameras on the Elwha River Restoration Project webpage.

Work will continue on the removal of both Elwha and Glines Canyon dam until the end of this month, when a “fish window” will shut down operations on the water. Work will shift to demolition of penstocks, powerhouses and other structures — work that will not release sediment into the river, according to the Elwha Blog provided by Olympic National Park. Construction in the water can resume at the end of the year.

At the Elwha Dam, contractors are blasting away to remove the left spillway foundation down into bedrock to form the downstream end of a diversion channel. The diversion channel is scheduled to be put into operation the week of Oct. 17, when the river will flow through the channel at an increased rate, drawing down Lake Aldwell.

Researchers poised for Elwha ecosystem studies

The Elwha watershed promises to be an outdoor laboratory for the revival of an ecosystem after two dams are removed from the Elwha River.

Dam removal began Thursday at Glines Canyon Dam, as I traveled to Port Angeles for a conference of more than 350 scientists and other interested persons. This group came together to learn about baseline studies conducted to date and to hear about anticipated changes in the ecosystem. Check out my story in Sunday’s Kitsap Sun.

Meanwhile, a controversy over a fish hatchery operated by the Lower Elwha Klallam Tribe threatens to erupt into a lawsuit. Several environmental groups have issued a 60-day notice to sue under the Endangered Species Act, saying raising steelhead from another area — Chambers Creek — could imperil the recovery of threatened chinook salmon and bull trout in the Elwha. See reporter Lynda Mapes’ story in the Seattle Times.

Will Stelle of the National Marine Fisheries Service, which oversees federal protections for salmon, said discussions about the hatchery are ongoing, but federal treaties assure the tribes a right to fish, and those rights cannot be ignored. A five-year moratorium on fishing has been imposed, but tribal officials say they may need hatchery-reared fish when fishing resumes.

About a year ago, I briefly described the restoration plan for each species — including salmon and steelhead — in a package of stories for the Kitsap Sun. See “Elwha Project Expected to Blast Open Nature’s Door to Bountiful Fish Runs.”

As for last week’s Elwha River Science Symposium, it was a remarkable group of researchers who discussed all aspects of ecosystem restoration, from physical processes like water and sediment, to all kinds of plants and animals. To get a taste of the presentation, read through the conference abstracts (PDF 584 kb).

I mentioned a few of the presentations in Sunday’s Kitsap Sun, and I could talk about them for hours. There was one presentation about birds that surprised me, and I wanted to share some of the conclusions with you.

John McLaughlin of Huxley College at Western Washington University explored the question of how birds might help restore vegetation in the reservoirs and flood plains associated with the Elwha and Glines Canyon dams.

Of 39 major native plants in the watershed, 23 have their seeds dispersed by birds. That’s 59 percent of the plants of interest. If managers could get the birds working for them, they might not need to plant as much vegetation by hand.

That 59 percent is higher than most temperate regions of the world, where normally birds disperse seeds from 25 to 40 percent of the plants, McLaughlin said. But it’s a lower percentage than for most tropical regions, where birds may disperse up to 90 percent of all the plants in the area.

By watching birds fly from vegetated areas to more barren areas and collecting samples of their scat, McLaughlin found that robins disperse more seeds than all other birds combined. In fact, the total was close to 100 percent for robins. While there are plenty of other bird species in the ecosystem, most typically do not fly from one habitat type to another, McLaughlin told the gathering.

He also found that most of the seeds deposited by robins ended up in and near logjams and piles of woody debris.

“Birds are agents of restoration,” he told the group, “but for them to work with us, you have to give them what they need, and that’s large woody debris.”

If one wants to use birds to replant the forest, the first step is to consider which plants you want to disperse, he said. Then downed trees and limbs could be pulled together into a pile, or one could simply leave existing piles in strategic locations. The woody piles must be located far enough from the desirable plants that the birds can make a difference in dispersing seeds. But if the piles are too far away, the birds may not cooperate with the plan.

As for the concern about birds dispersing invasive plants as well as desirable ones, many of the undesirables were removed from the area around the dams in preparation for dam removal. The concern about invasives is reduced further by understanding that only five of the 20 invasive plants are dispersed by birds.

Chipping away at historic Glines Canyon Dam

The contractor for the Elwha dam removal project jumped right into the job yesterday, pounding away at the upper Glines Canyon Dam with a hydraulic hammer mounted on an excavator, which was sitting atop a barge.

By this morning, a good-sized chunk of concrete had been eaten out of the dam, as you can see in the photo below. This picture was taken by one of six webcams that are focused on the two dams. As I mentioned in Water Ways on Aug. 16, this could be the best seat in the house for the deconstruction of the two dams.

Webcam at Glines Canyon Dam / Olympic National Park photo

On the Elwha River Restoration Project webcam page, click on “slideshow” below “Glines Canyon Dam” to get a time-lapse video of all the shots beginning Sept. 4, about two frames per hour during daytime.

At slide 213, you will see the first chunks taken out of the dam yesterday at 10:18 a.m. Use the controls at the bottom to slow down the slideshow to one frame per second, or march through the slideshow frame-by-frame to get a good view of the action.

While these photos will be fun and interesting for everyone to follow, they are an essential part of the monitoring program to ensure that sediment trapped behind the two dams erodes according to plan. I’ll talk a little more about this plan in a story I’m writing for Sunday’s Kitsap Sun.

Olympic National Park’s “Dam Removal Blog” describes the chipping process, including the use of shears to cut steel rebar inside the dam. Workers will chip away a few feet of concrete at a time until reaching the water line. At that point, notching will begin to carefully control the lowering of the water level.

Reporter Tom Callis of the Peninsula Daily News does a nice job describing the start of the actual work. An accompanying video provides the sounds at the start of this historic demolition project.

Also, if you haven’t heard, a formal ceremony to commemorate the removal of two dams on the Elwha River will be shown in a live webcast beginning at 11 a.m. tomorrow.

The ceremony itself, which will be held near the Elwha Dam, is limited to 400 invited guests. But anyone may watch from a big screen at the Port Angeles City Pier or on a special web page accessed through the Celebrate Elwha! website. The webcast is sponsored by the law firms SNR Denton and Perkins Coie.

Speakers at the ceremony will include Gov. Chris Gregoire; U.S. senators Patty Murray and Maria Cantwell; U.S. Rep. Norm Dicks, D-Belfair; Secretary of Interior Ken Salazar; Lower Elwha Klallam Tribal Chairwoman Frances Charles; and Olympic National Park Superintendent Karen Gustin. Musicians also will be featured.

Activities will continue Saturday and Sunday in Port Angeles as part of a weeklong celebration. Live music, artists, food and educational activities will be featured. For a full schedule of events, visit the website Celebrate Elwha!

Stay connected during demolition of Elwha dams

I’m looking forward to watching the two dams on the Elwha River being dismantled — and I won’t have to leave home.

In this July 9 photo, water was pouring through the spillway gates of Glines Canyon Dam. Since then, the reservoir has reached a low of -18 feet pending demolition, and the spill has declined.

Sure, I’ll try to make a few trips to Port Angeles and up the Elwha valley to see what I can see at various times. But webcams placed in strategic locations may actually be the best view around.

We won’t be able to judge the quality of the view from the webcams until they are installed later this month. At least that’s the proposed timing, according Olympic National Park officials who are doing their best to help people share the experience of dam removal.

I outlined the options for viewing and information gathering in a story in Sunday’s Kitsap Sun. In addition to webcams, park officials are working to find ways for people to stay connected with the project, both in person and on-line, as I describe in my story.

For ongoing information, there is Facebook, a blog and general information about the dams and dam-removal project.

Not to leave out fun, culture and education, a weeklong celebration is being planned about the time the contractor gets the go-ahead to work in the river on Sept. 15. For a calendar of events, go to the Celebrate Elwha! website.

Meanwhile, reporter Lynda Mapes of the Seattle Times was able to capture the sites and sounds of the changing environment as the declining water levels reveal conditions never seen before without scuba gear.
