By using a thin nylon rope longer than the depth of borewell firmly attached to a small sized stone (2 inches) or metal ring ( a small automobile bearing is ideal for this purpose) in one end is used for finding both the water level and total depth of the borewell. While leaving the stone/metal block attached to the rope into the borewell, when reduction in the weight of the stone is felt due to buoyancy of water after it strikes water surface, mark the point on the rope and remove the entire portion of rope let inside the borewell to measure for the water level from the ground., then start writing!
Measure the depth of water .
