Arsenovsky spring.
On the territory of the Orda village in the Perm Krai there is an unremarkable pond. From above it may seem overgrown and lifeless, but its unimaginable landscape is hidden under the water.
Arsenovsky Karst spring is located on the outskirts of the Orda village on the right bank of the Kungur River, near the village of Arsenovka, which is now a part of the village. The spring, also known as the Arsenovski creek, was dammed in the 70s. More than 300 liters of water comes from the pond into the Kungur river every second.
Just 700 meters from the spring there is the longest underwater cave in Russia - Ordinskaya Cave.
Arsenovsky Karst spring is a unique site for diving on the map of the Perm region.
