Determination of Groundwater Inflow to Prairie Lakes Using Remote Sensing

This study was designed to find the locations in Big Quill Lake, Saskatchewan, where the transfer of surficial and aquifer ground-water occurs in the lake bed. Using the findings of a geological survey done between 1966 and 1969, and combining the results of the remote sensing techniques of LANDSAT-1 airborne radio phase detection (EPHASE) and infrared line-scanning, it proved possible to locate nine areas at which inflow of groundwater is assumed to take place. Together these nine locations comprise an area of four square kilometers (1.5 mi2) in a lake that covers 250 square kilometers (100 mi2). In addition it was possible to separate these nine groundwater locations from such dynamic events as spiral currents (a tenth anomaly zone) and peninsula building bottom currents.
