Why is the lake being treated?

Spanaway Lake is an important resource that provides many recreational, aesthetic and habitat benefits. In recent years, aquatic weed growth and harmful algal blooms have had a negative impact on the lake. In response, Pierce County worked with the community to develop an Integrated Aquatic Vegetation Management Plan (IAVMP) in 2020 to help address invasive aquatic weeds. The IAVMP identified chemical treatment with herbicides as the optimal strategy for weed control.
