5203 |a"Measurements between 1964 and 1971 of piezometric levels in 35 piezometers installed in 9 groups in a multiple aquifer system and in unconsolidated sediments in a section across the valley of the South Saskatchewan River near Riverhurst, Saskatchewan, have revealed increased piezometric pressures as a result of the creation of Lake Diefenbaker. The increases in pressure, which vary with the water level in the reservoir, reflect a hydraulic connection between the aquifers and the reservoir, and not a classical loading effect. The stability of the area immediately downstream from the dam may have been adversely affected by these pressure increases. Groundwater discharge rates have been reduced significantly, and some loss of water from the reservoir appears to take place"--Abstract, p. vi.
