From the Introduction:
"The purpose of this study was twofold, one to try to determine the groundwater flow into and from Okanagan Lake and the groundwater potential of the main valley-fill deposits, particularly in the area from the north end of Okanagan Lake to the town of Enderby on the Shuswap River, and two, to determine the groundwater component of six selected sub-basins to more fully understand the hydrologic budget of the Okanagan River Basin."
