PHOSPHORUS REDUCTION

In collaboration with our partners, the GLA implements solutions to reduce the lake’s incoming phosphorus pollution—which impairs Green Lake’s water quality, fueling plant growth and degrading conditions for both our community and aquatic animals.

We’re borrowing it from our grandchildren.”
