A new chapter in local history begins Saturday.
At 11 a.m. Sept. 17 a formal ceremony will mark the start of a $27 million, three-year demolition effort to bring down the Elwha River dams. It is the largest dam removal project in U.S. history and plays a key role in a much larger undertaking: the restoration of the Elwha River.
Once a river of legendary fish runs, the construction of the Elwha Dam in 1913 and Glines Canyon Dam in 1927 cut off salmon spawning to all but the lowest five miles of river. A 1996 impact statement by the National Park Service estimated the number of native salmon spawning in the river dropped from 380,000 before the dams to 3,000 by the 1990s.
The loss of robust salmon runs, a source of food and income, hurt the Lower Elwha Klallam Tribe.
Thomas Aldwell was an entrepreneur who saw the Elwha River for its potential to generate massive amounts of hydroelectricity at a time when the growing Port Angeles economy provided a huge demand.
Aldwell formed the Olympic Power Company and began constructing the Elwha Dam five miles from the mouth of the river in 1910. The foundation of the dam was faulty, though, and in October 1912 it failed and washed out to the valley below.
After acquiring more financing, Aldwell began reconstruction in 1913 and the final product was a 108-foot dam capable of supplying electricity to the pulp mills of Port Angeles. The dam created the Lake Aldwell 2.5-mile-long reservoir.
Though state law required fish ladders be constructed with dams, Aldwell bypassed the requirement by building a hatchery, which closed in 1922 after operating only seven years.
Demand for more power led to the 1925-1927 construction of the Glines Canyon Dam by the Northwestern Power and Light Company eight miles upstream from the first dam. The Glines Canyon Dam is 210 feet high and, like the Elwha Dam, does not have fish-passage facilities.
Though the dams provided power to cities as far as 60 miles away, the negative effects on the salmon population along with impacts on land in the Olympic National Park, such as erosion of the river bank, began to change perspectives by the 1980s.
By the late 1990s, the dams no longer were a major source of power. According to a 1994 report, the dams provided just 38 percent of power for one Port Angeles mill by the mid-1990s. The 1992 Elwha Restoration act stayed the Federal Energy Regulatory Commission license applications for the dams, which set the groundwork for what is now a $327 million ecosystem restoration project.
The figure includes the cost of purchasing both dams and hydroelectric plants in 2000, tearing them down, constructing two water treatment plants and other facilities to protect water users, and constructing a fish hatchery completed in May 2011, flood protection facilities and a greenhouse to cultivate native plants for revegetation.
The dams were cut off from the Bonneville Power Administration on June 1 and the enormous turbines came to a halt. The Lake Mills and Lake Aldwell reservoirs were lowered 18 feet over the summer.
Diversion channels, cofferdams and other measures are in place to allow further drainage of the water.
Next, Barnard Construction Company of Bozeman, Mont., will dismantle the dams over a period of up to three years under a $26.9 million contract with the National Park Service. Once the dams are down, the river can return to its original channel and the site will be recontoured and revegetated to resemble what it looked like before the dams.
