Explanation:
Detailed explanation-1: -In the wild, scientists have observed beavers making repairs and additions to human-made dams. Beavers hate the sound of running water. It makes them think there could be a leak in their dam. If they hear running water, they will often work day and night to find the leak and repair it.
Detailed explanation-2: -Beavers are best known for their unique dam-building ability, which enables them to modify the habitat to meet their needs. By cutting sticks and branches and shoving them into the stream bottom and then piling mud and other debris on top, beavers are able to dam a stream and create a pond, or beaver flowage.
