Operation Flood, launched on 13 January 1970, was the world's largest dairy development program and a landmark project of India's National Dairy Development Board (NDDB). It transformed India from a milk-deficient nation into the world's largest milk producer, surpassing the United States of America in 1998 with about 22.29 percent of global output in 2018. Within 30 years, it doubled the milk available per person in India and made dairy farming India's largest self-sustainable rural employment generator. It was launched to help farmers direct their own development and giving them control of the resources they create. All this was achieved not merely by mass production, but by production by the masses; the process has since been termed as the "White Revolution".If there was one technological breakthrough that revolutionized India's organized dairy industry, it was the making of skim milk powder out of buffalo milk. The man who made this possible was Harichand Megha Dalaya.The Anand Pattern Experiment at Amul, a dairy co-operative, was the engine behind the success of the program.

Dr Verghese Kurien, the chairman and founder of Amul, was named the Chairman of NDDB by Prime Minister Lal Bahadur Shastri. Kurien thrust the program towards success and has since been recognized as its architect.
