Geological and hydrological natural monument of regional significance "the Red Lake", located near the village of Red Priozersky district of the Leningrad region, was organized in 1976. State control is exercised by the Government of the Leningrad region, submitted by the Committee on natural resources and environmental protection of the Leningrad region.

In order to get to the monument you need to catch a train from Saint-Petersburg to Zelenogorsk, then a bus to the village of Light or the village of Korobitsyno.

The area is 1650 hectares, of which water area of the lake is 750 hectares. This area is declared a natural monument for the preservation of the lake, in the sediments which accumulated iron and manganese, relict basin, which is dedicated to ancient tectonic concave shape (depression) in the crystal base and rare species of animals and plants.

Near the territory of the "red Lake" is a ski resort that is a great prospect for the development of tourist and sports infrastructure.

The Red lake belongs to the basin of the river Vuoksi, which ends 24 of the watercourse of which the Central one is the river Wanderer, but only one flows the river Red. Lacustrine basin stretches from North-West to South-East. The length of the lake is 6, 9 km, average width – 1, 3 km and maximum depth of -14, 6 meters. The catchment area is equal to 168 km2. Surface runoff in positive part of the water balance of the lake of the reservoir is 86, 9%.

The Red lake is a classic example of lakes, the sediments of which are concentrated deposits of manganese and iron. Most of the manganese enters the reservoir, predominantly, with water of rivers and streams in colloidal and dissolved States. The main part of the manganese is thrown out from the lake to the Red river.

The coastal area is partially overgrown with reeds, reeds, horsetail grass, pondweed, rush, the pod. For lake tends to reduce the flowage and eutrophication. Eutrophication is one of the manifestations of anthropogenic impact, which is the deterioration of water quality, violation of an oxygen mode, the disappearance of valuable species, the deterioration of the terms recreation, etc. the shores of lake partly covered by forests, which are dominated by different types of pine forests, mixed coniferous-small-leaved forests and spruce forests. Partly they are occupied by human settlements and agricultural land. Reed beds occupy a large area on the banks of the reservoir.

The Red lake is rich in fish, which is represented by pike, bream, burbot, whitefish, sculpin the sculpin, minnow, smelt. Through a complex of tributary rivers and streams fall into the lake brown trout, and lamprey. A very interesting element of the benthos are different types of bivalves. Live in the lake-glacial relict crustaceans: Pontoporeia, misida, pallasea.

The main protected objects of the geological and hydrological nature monument "the Red Lake" sediments are iron and manganese, the coastal area of the reservoir, a rare animal and plant species: brook trout, lamprey, relict crustaceans, sedge Omsk, backache meadow, Laden trehyadernye.

On the territory of the natural monument is not allowed to do all kinds of construction, reclamation and mining activities, leading to a change in the hydrological regime, prohibited exploration activities, mining, laying of all types of communications, wastewater disposal, littering.
