Waterways Ireland, the North / South Implementation Body for the inland navigable waterways systems, was established in 1999. As provided for in the Belfast/Good Friday Agreement, the Body was formally established by means of an international treaty made on 8 March 1999 between the British and Irish Governments. This treaty was given domestic effect, North and South, by means of the North/South Co-operation (Implementation Bodies) (Northern Ireland) Order, 1999 and the British-Irish Agreement Act, 1999 respectively.
