The SC’s order last week, directing the Centre to immediately take up construction of the incomplete Sutlej Yamuna Link (SYL) canal, has come as a blow to the Punjab government. The canal, to carry Haryana’s share of the surplus waters of Ravi and Beas, is an emotive issue in both states. Opposition Akalis are threatening agitations if construction is started. Three-fourths of the 212-km canal was near completion when work was stopped in 1990, after the chief engineer was killed by militants. Already troubled Punjab CM Amarinder Singh has rushed to meet PM Manmohan Singh. Punjab wants the Centre to set aside the Eradi Tribunal award of the ’80s, reasoning that with water shrinking over the years, Haryana’s share needs to be examined by a fresh tribunal.
