Lake Cleanup Continues After Historic Flood: Recent historic flooding of the Cedar River has washed hundreds of trees, large logs, and other debris into Lake Washington, creating severe navigational hazards for boaters and seaplanes. The Mercer Island Police Department’s Marine Patrol Unit is using its capabilities to lead the cleanup effort in its area of jurisdiction, which includes the waters around Renton, Bellevue, and the Island.

This effort will continue through the spring, primarily because of the tedious and time-intensive nature of the process to locate, secure, and tow large logs to shore, which are then hauled away by Public Works crews. To date, approximately 800 cubic yards of material has been removed from the lake. To facilitate this operation, the Mercer Island Boat Ramp remains closed.

To report free-floating logs or other large debris, call the non-emergency line at (425) 577-5656 or leave a message at (206) 275-7909. Residents who have logs that have collected along private docks and shorelines are encouraged to remove them as soon as possible (contact a landscape company or boat tow service), as they can drift back into open water and create additional hazards.
