ii. The calibrated recharge values reflected relatively higher recharge rates in
areas of higher hydraulic conductivity (sandy till, sand channels, aeolian
deposits) than areas of lower hydraulic conductivity (ground moraine or
glaciolacustrine deposits). This relationship is well established (see Walton
1985, pg 56), and has been demonstrated by other EIAs conducted in the
region and other studies in similar hydrogeologic settings in Alberta
(Farvolden [1963]; Geoscience Consulting Ltd. [1976]; Hydrogeological
Consultants Ltd. [1977]; Alberta Environment [1978]).

Request 18f On pages 26 to 28, general descriptions of boundary conditions are provided.
However, the input parameters for different boundary conditions are not
described (e.g., river stage elevations, river bottom elevations, and drain
elevations). For riverbed and lake bed conductance, the vertical hydraulic
conductivities used are 1 x 10-6 m/sec and 1 x 10-8, respectively.
i. Provide the different input parameters of the boundary conditions, and
describe the methods used to define the boundary input parameters,
including the river and lake conductance values mentioned above.
