Berkhomut, Natural monument in Ishimbaysky District, Russia.

Berkhomut is a karst spring of the rising-pressure type, 600 m south of Khazinovo in Ishimbaysky District. It emerges from the carbonate rocks of Mount Tirmen-Tau at an absolute elevation of 219.5 m, with hydrocarbonate-calcium water. Since December 1973 part of the spring has been capped by a concrete sarcophagus and its water piped 50 km to Sterlitamak, so the spring itself is no longer visible.

In 1770 the naturalist Ivan Lepyokhin recorded an earthen dam about 4 m high at the spring, powering a mill with two millstones. A 25 kW hydroelectric station was built here before the Great Patriotic War. In December 1973 part of the spring was capped with a concrete sarcophagus and its water piped 50 km to Sterlitamak.

The name Berkhomut (Bashkir Bergamyt) comes from a legend: a local man's horse drowned in a nearby lake, and its bridle was later found in the spring. Until 1973 the water flowed into the Khazhinovskaya Shida and then the Salauka; it is cold and sweet-tasting, and the Berkhomut beer is brewed from it.

The spring lies 600 m south of Khazinovo in Ishimbaysky District. Since December 1973 its water has been capped under a concrete sarcophagus and piped 50 km to Sterlitamak, so the spring itself can no longer be seen; the outflow reaches the Khazhinovskaya Shida. Plan to view the site from outside the capped structure.

The spring's name comes from a Bashkir legend: a local man's horse drowned in a nearby lake, and its bridle (bergamyt) was later found in the spring. Since December 1973 a concrete sarcophagus has capped part of the spring, and its water is piped 50 km to Sterlitamak, so the spring itself can no longer be seen.
