Here is the bore hole pattern (detail) we used and the approximate
drilling depths for each hole. It was important to consider the relative
distance from the surface of the rock to (what will be) the splash pool
below the waterfall.
Shown (Right) in Section, West to East, is the desired effect of the
holes and the splash pool depth.
The Section, (Right and below), depicts the need to relocate the existing
stream flow channel to the south.
