The diggers have left the reshaped island in Henley Lake but the black-billed gulls have stayed.
Masterton deputy mayor Graham McClymont said yesterday the diggers returned to the mainland on Tuesday, having put the finishing touches to how the island was to look, apart from being planted up.
The water course to be used by dragon boaters and waka ama crews has been formed and Mr McClymont said both clubs had offered to help with replanting the island.
"As it was, we saved all the native plants disturbed by the work that was done and have replanted those," he said.
The digger work was done within budget, thanks to Geoff Busch and Graeme Edwards of Central Earthworx, who kept to the agreed price even though the job ran over by a few days.
