GRAYS HARBOR COUNTY DAM SHOW SIGNS OF DISTRESS: A dam more than a century old in Lake Sylvia State Park in Grays Harbor County is “showing signs of increasing stress,” the county’s emergency management department said Tuesday.
The dam, which is east of Aberdeen and north of Montesano, hasn’t failed, “but could continue to worsen if weather conditions persist,” the department said.
The dam appeared to be a significant hazard to nearby roads and property, said Jimmy Norris of the Washington State Department of Ecology. There is no safety concern for people, should the dam fail, as there are no nearby residences at risk.
Nevertheless, Washington State Parks advised residents in the Sylvia Creek area downstream in Montesano to prepare for additional flooding and be prepared to move on short notice.
