Description: The control of seepage from irrigation canals and dugouts to conserve water and to protect arable lands is an important consideration on the Canadian Prairies. Seepage from unlined irrigation conveyance systems and dug outs wastes valuable water, and often causes adjacent lands to be unproductive because of waterlogging and salt accumulation. This may necessitate the construction of expensive drainage systems for reclamation. One way to save water and reduce seepage is to make certain that conveyance systems and storage reservoirs are as watertight as it is economically feasible to make them. Lining with relatively impervious materials seems best to meet this requirement. In the early 1950s the Prairie Farm Rehabilitation Administration (PFRA) became increasingly concerned about water losses from canals and dugouts and the damage caused by seepage to agricultural lands and other property. The Soil Mechanics Division of the PFRA was given the responsibility of studying and reporting on the suitability of canal linings previously in stalled by the PFRA. At the same time, the Drainage Division of the PFRA was to conduct studies on water loss from existing canals, to recommend where linings should be placed, and to evaluate their effectiveness.
