Dzelindskiy spring is a hydrogeological natural site of federal rank. This spring consists of two hydrothermal outflows 2 km away from each other. The first outflow is located 38 km up from Verkhnyaya Zaymka village, in a tectonic rift which is now in the form of a ledge of 6-8 meters high.
The second outflow is on the left bank of Verkhnyaya Angara river on the opposite side of Dzelinda river mouth. Hot gas water outflows are located on the same rift. Sulphate-hydrocarbonate water comes out to the surface at a distance of 50 m. Water mineralization is 0,56 g/l. The water temperature varies from +32°С to +44°С. Water discharge is 10 liters per second.
