The Royal Dublin Golf Club clubhouse was used as officers' quarters and considerable damage was done to the building and, particularly due to trench warfare practice, the island environment as a whole.

The first drive-in at what was a nine-hole course until 1989, took place on 1 July 1921. 1931 - present In 1931, a plan was proposed to develop the island and the waters between it and the coast. Called the "Blue Lagoon Scheme," this would have included dams and sluices at the Wooden Bridge and Sutton Channel, maintaining a high water level behind the island, which itself might hold some housing or tourism facilities.
