The dam project, drafted in 2018 and based on a former military training site south of Prague, had been delayed by land negotiations. Local beavers built several dams, saving the government more than one million euros.

For years, authorities debated building a barrier to protect the Klabava River, south of Prague, from sediment and acidic water spilling from nearby ponds. A dam would have solved the problem, but the project stalled due to financial and bureaucratic problems since 2018.

Beavers have saved the Czech government and its citizens $1.2 million, by flooding an area, where a dam was planned.
