Saint Lake is part of a protected natural area designated as the 'Kosino' landscape reserve.
The lake reaches a maximum depth of approximately 5.5 meters in certain sections.
Its formation is attributed to the Valdai glaciation period, which carved out several depressions in the local terrain.
Historical records indicate the lake was once used for irrigation and fish farming by the manor estates of the 18th and 19th centuries.
The lake's water level is partially maintained by underwater springs, which influence its unique mineral composition.
Saint Lake is a natural reservoir located in the Kosino-Ukhtomsky District on the border of Lyubertsy, Moscow. It is one of the three glacial water bodies forming the historic Kosino Lakes complex, alongside White Lake and Black Lake. The lake occupies a circular depression formed during the retreat of the glaciers, contributing to its distinct geological history. Historically, the area was part of the estate of the Sheremetyev noble family, who significantly influenced the local landscape. The surrounding shoreline features a mix of sandy patches and overgrown marshland, reflecting its ecological status as a protected area. Recent urban development in the adjacent districts has led to infrastructure improvements along the perimeter, including designated walking paths. The water quality is monitored, though swimming regulations vary by season based on sanitary standards. The site serves as a local recreational hub for residents of both Moscow and the Lyubertsy urban area.
The wooden pedestrian walkway on the northern bank offers a clear view of the water reflecting the surrounding forest.
Bring insect repellent during the summer months, as the marshy areas attract mosquitoes.
Stick to the marked wooden boardwalks and paved paths to protect the sensitive shoreline vegetation.
Check the local municipal website for the most current water quality status before planning any water-based activities.
Do not attempt to swim if local authorities have posted signs indicating poor water quality, which can happen periodically.
Respect the local wildlife, keep noise levels low, and dispose of all waste in provided receptacles to maintain the nature reserve status.
