Does the depth of the ground water table vary in every region?

    Depending on the geological makeup of a region, there can be vast differences. Along major rivers and streams, depth of groundwater may be under a foot, while maximum depth is about 1,200 feet under Larch Mountain. Areas with terrace deposits, such as Portland, have an average depth to water of 100 feet, which is greater than normal. Human construction can also have an effect on depth to water, often bringing it closer to the surface. The great many factors involved ensure at least some variation in the depth of groundwater across large distances.

    Yes, and even within regions the depth of groundwater varies depending on the where bedrock is in relation to the earth’s surface.  Note in the image below how the depth of ground water varies with the topography.
