Lake sediments safe in Kenmore area

KENMORE — Public areas along Lake Washington’s northern tip are safe for swimming and other in-water recreation, according to assessments of lake sediments and water quality.

Findings will be presented at a public meeting set for July 11 at Kenmore City Hall beginning at 5:30 p.m. with an informal open house. A presentation and question-and-answer session will begin at 7 p.m. The meeting will focus on:

• City/state sediment study: Kenmore and Ecology jointly funded a study that examined sediment samples at Log Boom Park, Kenmore Navigation Channel, Kenmore Industrial Park, the lower reach of the Sammamish River, including the Department of Fish and Wildlife (WDFW) boat launch, and at Lake Forest Park’s Lyon Creek Waterfront Park. Concentrations of dioxin and other toxic substances in the sediments at most of these locations were consistent with or lower than background levels found in soil in other parts of the Seattle urban area.

• Department of Health assessment: The Washington Department of Health evaluated the sampling study data and concluded that contact with sediments outside Harbour Village Marina and  Northlake Marina  is not expected to harm people’s health

• Kenmore Navigation Channel dredging project
