In October 2019 GWC volunteers together with our indigenous partners at the annual Bioneers Conference launched a 100% biological (no plastic or foam) Bio-Raft, currently tied near the Civic Center Lagoon dock. This new floating island biofilter was constructed of bamboo, cordage and willow branches.

GWC will be moving this bio-raft alongside the other newly launched floating island to compare and contrast their growth rates and ability to clean the water in that area.

We thank our wonderful partners including Marin County Parks for their help and support in our CCWR (Civic Center Watershed Restoration) project!
