If you want to clean a dam of all silt and debris, the best way is to use an excavator with a rake on its boom. This machine has a large bucket at the end of its arm for removing soil from the bottom of the reservoir. A telescopic arm ends in a rake that gathers up any gravel or sludge in its path.

A dam can become clogged with sediment over time, which can reduce its storage capacity and affect its ability to regulate the release of water. Clogged dams can also increase the risk of flooding.

A firebreak, also known as a "control line", is an area of earth where the vegetation has been cut or burned to stop the spread of oncoming fires. By reducing fuel load through controlled burning or mechanical damage, it helps contain wildfires by depriving them of combustible material ahead of the main fire front. By doing this, you can help protect your home against fire. 

A bulldozer is the best machine for clearing land. It has a large blade on the front for pushing earth and debris out of the way. The blade can also be used to level the ground. A bulldozer can even be fitted with a claw for uprooting trees and stumps. It’s powerful and can be used to remove thick vegetation, trees and other surrounding debris.
