Summary

Pursuant to the recommendation contained in paragraph 17 of the Report of the Indus Discharge Committee 1929 two Superintending Engineers were appointed by the Governments of Bombay and the Punjab respectively to investigate the effects of the Bhakra Storage Scheme on the Inundation Canals of the Indus between Mithankot and-Sukkur. [...] the reach between the junction at Harike with the Beas and the junction with the Chenab at Panjnad was entitled to claim up to the limit of the santioned canal head capacities in cuseos the supply entering the Gharra Reach from the Beas together with any surplus that may flow into the Ghana Reach from the Sutlej after the irrigation requirements on the Sutlej above the junction of the Beas [...] 1. In considering the effects of the proposed Bhakra withdrawals on the water levels in the Indus above Bukkur one of the questions which arises is the probable effect of the Sukkur barrage on the water levels in the Indus above it. [...] It is not necessary to repeat these changes in detail suffice to say that the first effects of the weir were (a) to flatten the slope of the river upstream and (b) to lower the level of the water surface downstream ; the latter effect was due both to a reduction of the amount of water passing below the weir and also to a degradation of regime levels. [...] 5. In regard to the initial effect (a) ; this appears directly from the gauge graphs and records at Patial although the data only go back to 1886 and therfore the earlier years of the rise are not shown but the average slope of the river prior to the construction of the weir is known and the slope is now in the high water months practically the same as it was at that time.
