Istra Reservoir, Water reservoir in Moscow Oblast, Russia

The Istra Reservoir is a water storage basin in Moscow Oblast created by damming the Istra River. The water body features a complex shoreline with numerous inlets and bays, surrounded by forested banks in various sections.

The basin was created in the 1930s through dam construction to meet Moscow's growing water needs. This development marked one of several major water infrastructure projects undertaken in the Moscow region during that era.

The reservoir shores feature numerous vacation complexes and summer camps where Moscow residents spend their leisure time during warm seasons.

The site is open year-round, though summer months draw the most visitors for water activities and relaxation. Multiple access points along the shoreline offer different facilities, so exploring different areas helps you find what suits your interests.

The dam creation involved flooding tributary valleys, which produced bays with varying water conditions and local currents in different sections. This natural variation means visitors encounter quite different landscapes and water characteristics depending on which area they explore.
