WA State Parks has completed the San Juan Islands buoy maintenance project, part of a 5-year initiative to repair or replace 259 mooring buoy in the greater Salish Sea. The work involves installing modern, eco-friendly helical anchors (see diagram below) and replacing old buoy gear to ensure boater safety and protect eel grass.
Of course, you can find WA State Marine Parks here on the PNW Boaters Guide. And an easy way to locate state park buoys out on the water is with the new OnBuoy app (available for iOS devices in the App Store).
