The World’s largest Beaver Dam – At 2,790 feet long it was discovered through satellite imagery and is twice the length of the Hoover Dam, at 1,244 feet long.Beavers are the second-largest rodent in the world (after the capybara) and are closely related to squirrels. Known as "nature’s engineer, the beaver’s dam-building activities are important to natural water flow and erosion control. Beaver dams are created in order to build their homes in the resulting ponds (known as beaver lodges). The lodges serve as protection against predators (such as coyotes, wolves and bears) and provide easy access to food during winter. Beavers always work at night and are prolific builders, carrying mud and stones.
