Brynskoe Reservoir, reservoir in Russia

Brynskoe Reservoir is an artificial lake on the Bryn River in the Duminichsky district of Kaluga Oblast, with a water surface of 790 hectares. The Urushka River flows into it. The reservoir is used for pond fish farming by the SPK Brynsky collective, raising carp and bighead carp.

Nikita Demidov built the dam on the Bryn River between 1722 and 1724 to supply the Bryn hammer works. From 1822 to 1896 the reservoir served the Bryn cloth factory. A flood destroyed the dam in 1933, and it was rebuilt in 1966–1967 for a fish-farming enterprise.

The reservoir's name comes from the Bryn River, on which its dam stands. Since 1966–1967 it has served the SPK "Bryinsky" fish-farming cooperative, which raises carp and bighead carp in its 790 hectares of water. The Urushka River also flows into it.

The area is easily accessible by local roads with parking available near the water. The flat terrain with gentle hills makes walks and shoreline activities convenient for visitors.

The reservoir's surface covers 790 hectares on the Bryn River in Duminichsky District. It is fed by the Urushka River and used by the SPK "Brynsky" cooperative for pond fish farming, raising carp and bighead carp.
