Gumbel and GEV flood frequency curves for river Jhelum at Rasul are developed using 67 years flood 1922-88 Annual Maximum flood series. The GEV distribution is estimated by method of probability weighted moments. Its goodness of fit is seen by KS test. This distribution appears to be appropriate for modelling the flood data. The flood estimates at various return periods i.e. 4, 5, 7, 10, 20, 50 and 100 are worked out using GEV distribution. The estimated 100 years flood by this distribution is seen to be 1.24 millions cusecs while the barrage was designed to pass a maximum flood discharge of 0.85 million cusecs
