If you are looking to drill a water well, you want to know where to drill before going to the expense of drilling a water well. The big question is “how deep am I going to have to drill to find water in my area, and what depth is the water table (the level below which the ground is saturated with water.)” . Looking at water well records for your area is a good place to start. After viewing the records for your area you will see that the depth and yield ( gallons per minute ) vary greatly. Some of the wells may find water in a unconsolidated zone and some in fractured bedrock. Whether you are looking to find or locate, an underground lake, underground river, underground stream or creek, underground spring etc they are all classified as groundwater.
