Formosa Island

The island is one of the largest on the non-tidal river Thames with 50 acres (20 ha) of woodland.

Most of the land on Formosa Island is owned by the John Lewis Partnership, and forms part of the Odney Club country club owned by the company.

The adjacent Mill Island has the lock channel on the other side.

Beyond the lock channel is Sashes Island and the channel furthest from Cookham is Hedsor Water, the original navigation channel, which was blocked by the weir in 1830 when the lock was opened, causing loss of trade to then owner Lord Boston.
