The beavers have built at least four dams and they could not have chosen their location better. They built them on a bypass gully, originally excavated by soldiers to drain a former military base. This drainage system had a negative environmental impact, but the beaver-built dams helped to restore the area into a thriving wetland.

After plans stalled for a new dam in the Czech Republic, eight beavers saved the day seemingly overnight. “At this point, nothing that beavers do surprises me.”

Beavers in the Czech Republic ignored construction permits and completed a stalled dam project, much to the delight of officials.

Beavers have saved Czech taxpayers a cool $1 million by flooding a protected former army training site where a long-stalled dam was planned, a conservation official said on Tuesday.
