A beaver colony surprised officials in the Brdy region of the Czech Republic by building a dam that would have otherwise cost them over a million dollars.
Government officials had reportedly received approval to allocate 30 million crowns (approx. 1.2 million dollars) to the project, which was conceived as a solution to address water issues in the protected area.
However, after seven years, the project encountered an obstacle, as officials were unable to acquire the permits to continue building the dam.
One morning, they woke up to find that eight rodents had already done the job.

“The Military Forest Management and the Vltava River Basin were negotiating with each other to set up the project and address issues regarding ownership of land. The beavers beat them to it, saving us CZK 30 million,” said Bohumil Fišer, the head of the Brdy Protected Landscape Area Administration.
“They built the dams without any project documentation and for free.”
While the discovery occurred overnight, it’s likely that the eight beavers took longer than a day to complete the structure, Gerhard Schwab, beaver manager for the southern part of Bavaria, told National Geographic.

Schwab told the nature magazine that he believes the construction took a few weeks and no one noticed the work until it was completed.
Beavers are ecosystem engineers, meaning they modify their habitat and have a large impact on the landscape and other species.
In addition to providing protection from predators, beaver dams create habitats for multiple species, including fish, aquatic insects, herons, and mammals like moose and bison.
Though the government had approved $1.2 million for the dam, the project was halted after seven years because officials were unable to acquire building permits

Their impressive work—completed by using mud, rocks, and wood—can also serve as natural firebreaks and provide flooding control, as per National Geographic.
For instance, in the summer of 2018, after the Sharps Fire in Idaho, USA, valleys where beaver colonies roamed remained protected from the blaze.
“Beavers always know best,” said Jaroslav Obermajer, head of the Central Bohemian office of the Czech Nature and Landscape Protection Agency (AOPK).
“The places where they build dams are always chosen just right—better than when we design it on paper.”

Once on the brink of extinction due to hunting, Eurasian beavers are now reportedly protected, with their role in the habitat recognized in the Czech Republic.
The largest beaver dam can be found in Wood Buffalo National Park in Canada. It’s almost 800 meters long (approx. 2620 ft, the length of seven football fields) and holds back run-off water from the Birch Mountains.

Given the size of the dam, it’s believed to be the work of multiple generations of beavers in the park.
According to its official site, the Wood Buffalo Dam is so large that it can be seen from space.
People were stunned by how quickly the beavers had completed the structure
