Lake Loma Algae Control Plan
Snohomish County developed this plan in 2019 in coordination with community members in response to ongoing concerns of lake health. The goal of this plan is to provide the community with a road map to reduce phosphorus pollution, the underlying source of toxic algae blooms to the lake. Included in the plan are:
- Major sources of phosphorus to the lake
- Effective solutions to control the pollution and reduce toxic algae
- Cost estimates and benefits of each option
- Next steps for the lake community to implement the plan
If implemented, there will be long-term benefits to the health of Lake Loma including reduced occurrence of algal blooms, increased water clarity and improved dissolved oxygen levels in the lake. The lake community will now need to collectively decide if the benefits of the implementation plan are worth the required financial and time investment. The first step would be for interested residents to create a committee to review the plan and propose a path forward to the broader community. Click on the icons below to learn more.
