Dam removal on the Elwha River in Washington has been temporarily halted because massive amounts of sediment released from above the dams have clogged one of the city’s water treatment facilities.
One of the two dams on the Elwha has been completely removed. That’s released about 20 percent of the 34 million cubic yards of sediment stored up behind both dams.
But the muck, silt and debris been clogging the intake system at the Elwha Water Facility. The facility provides drinking water to Port Angeles as well as two nearby fish hatcheries and the nearby paper producer.
