The water level in the canal on July 21, 1978, was above the water table along the entire reach of the canal upstream from the Fall Creek aqueduct, which precluded the discharge of ground water into the canal. If the canal sides and bottom can be assumed to be permeable, then water can be assumed to be seeping downward from the canal into the deposits along the entire reach. Because of the highly variable lithology in the alluvial and outwash deposits underlying the canal, the seepage rate is probably also highly variable. Discharge was measured at selected points along the canal, and differences between successive measurements were calculated to determine the rate of water loss. The rate of seepage from the canal would be greater for stages and water temperatures higher than those at the time of the study and would be lower for stages and water temperatures lower than those at the time of the study.
