Kennedy, Executive Engineer in Punjab, PWD was in-charge of this canal system in 1895. The canal was not silt cleared for a long period. He recognised that the canal has attained stable stage and hence he pleaded that the velocity of flow has also attained critical stage. He studied nearly 20 sites on the stable reach of this canal system ...
