Mozhaysk Reservoir, Water reservoir in Moscow Oblast, Russia.

The Mozhaysk Reservoir is an artificial water body in Moscow Oblast that collects water from the Moskva River and channels it through a pipeline system serving the region. The water spreads across multiple bays and is bordered by forested shores, with varying depths and different coastal sections.

The reservoir was built during the 1960s as part of Soviet-era industrialization efforts to supply water to the growing population of Moscow Oblast. Its construction was part of a larger plan to manage and control the region's water resources.

Fishers and water sports enthusiasts regularly use the bays around the reservoir, especially on weekends and during warmer months. These activities shape the character of the shoreline and show how important the water body is to local recreation.

The reservoir can be accessed at several locations along the shore, with parking areas and boat ramps available throughout the day. Walking and cycling paths circle the bank, offering the clearest views during early morning hours.

The reservoir influences local temperatures and causes mist during early mornings and evenings, affecting conditions for surrounding agriculture. This effect is most noticeable in colder months when temperature differences are greatest.
