Why Green Lake Needs Bioswales

Every summer, the same headline: Green Lake closed due to toxic algae. Blue-green algae blooms fed by excess nutrients in the water. The lake doesn't exist in isolation - it's connected to the same watershed system that includes Ravenna Creek. Nutrients, sediment, and pollutants from residential properties flow into the system and eventually contribute to the conditions that trigger blooms.

Green Lake neighborhood has higher property values, an engaged community, and strong environmental awareness. People here already care about water quality - they see the consequences at the lake every July and August. The missing piece is connecting that awareness to what happens on individual properties.

Under every lot in the neighborhood is alderwood soil - loose on top, hardpan underneath. Lawn fertilizer, pet waste, automotive fluids - anything on the surface eventually washes into the storm system when water can't percolate through the glacial till. A bioswale filters that water on your property before it enters the system. If you care about the lake, start with your yard.
