In 1792 the four-mile Strabane Canal was constructed from the tidal waters of Lough Foyle at Leck, to Strabane. The canal fell into disuse in 1962. In June 2006 the Strabane Lifford Development Commission awarded a £1.3m cross-border waterways restoration contract. The project involves the restoration of one and a half miles of canal and two locks to working order. Work began on the Lough Foyle side of the canal in the summer of 2006, but by 2010 the partial restoration was deemed unsatisfactory and the local council refused to continue to maintain the canal.
