Dredging is a way to clean lakes. It removes extra dirt and plants from the bottom. This makes the lake deeper again. Special machines are used for dredging. These machines can work in water. They scoop or suck up the stuff at the bottom.

There are different types of dredging equipment:

• Dredges: These are boats with scoops or pumps.
• Excavators: These are like big shovels on boats.
• Suction devices: These use pipes to suck up dirt and water.

Each type of equipment is good for different jobs. The choice depends on the lake and what needs to be done. Dredging can be a big job. It takes planning and skill to do it right.
