Over half of the water supplied to the watercourse at Tubewell 56L was lost before it reached the farmer's fields. This loss was primarily through the upper porous portions of the banks and in the vicinity of junctions where banks were thin. The 35 farmers in the 900-acre area served by this watercourse were motivated to organize themselves to rebuild their own earthen watercourse, according to specifications drawn up by Pakistani engineers. Low cost concrete diversion structures were developed and installed at junctions to eliminate continued burrowing of soil and degradation of banks near the junctions. The improvements reduced losses to about one-half their previous values and increased deliveries to the fields by over 50 percent. This watercourse improvement appears to be an ideal component for a development program designed to increase crop production. However, farmers require further information on how to use this water and other inputs to optimize crop production if they are to obtain full benefits from this extra water.

Five Pakistan watercourse systems, selected from various areas of the Indus Basin, were evaluated during complete irrigation turn rotations while operating normally. This allowed quantification of the various types of water losses, including transient condition losses such as dead storage, bank wash-outs, outlet leakage, and high initial seepage into dry channel banks.
