Renovations continued through the first decade of the 21st century, and a project to restore the pond was commenced in 2000.[230] Four years later, the Conservancy replaced a chain-link fence with a replica of the original cast-iron fence that surrounded the Upper Reservoir.[231] It started refurbishing the ceiling tiles of the Bethesda Arcade,[232] which was completed in 2007.[233] Soon after, the Central Park Conservancy began restoring the Ramble and Lake,[234] in a project that was completed in 2012.[235] Bank Rock Bridge was restored,[236][237] and the Gill, which empties into the lake, was reconstructed to approximate its dramatic original form.[238] The final feature to be restored was the East Meadow, which was rehabilitated in 2011.[239]
