Lake Health

Lake Stevens is one of our community’s most treasured natural resources, and protecting its health and vitality is a top priority. By leveraging historic lake-level data, annual alum treatments to manage phosphorus, and targeted aquatic vegetation management, the city is taking proactive steps to ensure the long-term health of our lake. These efforts not only safeguard the lake’s ecological balance but also promote sustainable recreational opportunities for residents and visitors alike.

Community input is a vital part of these initiatives, as local knowledge and feedback help shape how we address emerging challenges and refine existing strategies. Whether it's accessing real-time data through our interactive lake-level dashboard, staying informed about alum treatment schedules, or learning about aquatic vegetation control, residents play a crucial role in preserving the integrity of the lake. Together, we can make practical and impactful decisions for the future of one of our city’s most iconic assets.
