The US Bureau of Reclamation (Reclamation) has installed over 4,000,000 m2 of geomembrane canal liners since 1986. Reclamation continues to evaluate the performance of new materials in new applications for canal lining. Recent installations in South Dakota, Washington, Nebraska and Oklahoma contain relatively new materials installed as either exposed or covered canal liners. Although the majority of geomembranes used as canal liners have been soil covered, since July of 1987, several geosynthetic systems have been covered with concrete or left exposed. Results from monitoring a soil covered polypropylene geomembrane in South Dakota, an exposed high density polyethylene geomembrane in Kansas, and an exposed very low density polyethylene geomembrane in Nebraska are reported. Geomembranes used as canal liners appear to reduce seepage in the canals when they are constructed in highly permeable or collapsible types of soils.
