There are many ways to find something from the bottom of a lake. Often times, the method selected will depend widely upon the type of lake that you are examining as well as the item that you are looking for that may be on the bottom of the lake. As such, experts, when hired to look for something on the bottom of an lake will provide a variety of different processes. One of these methods is called lake dredging which will be examined as the focus of this article. This is not as useful looking for smaller items such as jewelry. For this infrared scans and waterproof metal detectors are typically used to locate jewelry.
An example of this is lake dredging. What lake dredging is depends on the lake. In a small lake, lake dredging will occur often through a net or cage dragged along the bottom of the lake. This will be pulled through a certain section of the lake to determine which items have been located. If the item is valuable or you do not want it to be damaged, a net is often used to dredge the lake. As unfortunate as it is this is what is commonly done when looking for dead bodies that have been left in lakes after having been murdered or for individuals who have drowned in the lake. For larger lakes, different methods of lake dredging have to be performed. This often involves large boats with dredging apparatuses attached to them which handle most of the dredging by driving around a small area and dragging a device.
