Blackmans Lake Alum Treatment Scheduled to Begin on March 28, 2025

The City of Snohomish has announced an alum treatment at Blackmans Lake, scheduled to start on March 28, 2025, and expected to last for approximately six days. This initiative aims to improve water quality and is being monitored by environmental consultant staff to ensure effectiveness and safety. Although there are no restrictions on water use, the lake will be closed to the public for the duration of the treatment. Residents are urged to keep themselves and their pets away from the area to facilitate uninterrupted work by the contractor. The treatment is essential for maintaining the ecological balance of Blackmans Lake, which is a significant local resource.

The project is anticipated to conclude by April 2, with site restoration planned for April 3. Updates will be provided to the community if there are any changes to the schedule. For further details, residents can visit the Blackmans Lake Management page on the city's website.
