Some rural people and most well-diggers know that water can only be found at certain places in riverbeds. They can also give a rough estimate on how deep they have to dig before reaching the water-table.Their knowledge is based on the fact that certain species of trees and vegetation must have roots reaching down and into the water-table in order to survive droughts. This traditional information (based on Kenyan plants) is compiled in the table belowas an example. Make sure to find similar regional plants specific to your site area.
