Huge thanks to Sue Sisley for preserving her late brother-in-law Edward Gordon (Ted) Sisley’s amazing photo collection- and this vital Pakistan New Zealand friendship connection. Ted was a Kiwi engineer who spent a decade (1964–1974) working on Pakistan’s Indus Basin Projects: Mangla, Chashma, and Tarbela. As a Service Engineer for Bowmaker (Caterpillar’s dealer), he supervised repairs on earthmoving machines across all three iconic dam projects made possible under the Indus Waters Treaty. His photos capture more than machinery. They showcase Pakistanis and New Zealanders working side by side constructively on undertakings of great economic significance for Pakistanis, made possible by a Treaty till now seen by many as an example of successful application of international law. Ted passed in 1974, but his legacy lives on today in the dams that still stand and serve. This legacy is imperilled today by the weaponization of water by Pakistan’s neighbouring state, a co-signatory to the Indus Waters Treaty, India, together with threats to illegally walk away from the Treaty, divert Pakistan’s share of waters and dry up Pakistan’s reservoirs and rivers!
