Volunteers are needed to build Manufactured Wire Reefs, which are wire baskets filled with recycled oyster shells.  The project will take place at the Waddell Mariculture Center on Sawmill Creek Rd. in Bluffton on March 14, from 9 AM to 12 PM.  The MWRs will be placed along the shoreline of the May River by Bluffton Rotarians at a future date.
