Lake Seliger
Seliger (Ostashkovskoe) is a system of lakes on the Valdai Upland, on the border of the Tver and Novgorod regions. Russia.
Lake Seliger in the Russian chronicles of the 12th – 13th centuries. occurs under the name Sereger. The name of the lake is most likely of Baltic-Finnish origin, but its exact etymology remains a matter of controversy. According to one version, the name comes from the Finnish “Selkäjärvi” (“high lake”), according to another - from the Finnish “Särkijärvi” (“roach lake”). There is also an assumption that the name of the lake, translated from the Finnish selhea, is interpreted as “a transparent, indented lake”.
The water's edge is located at an altitude of 205 m above sea level. Lake Seliger is an alternation of stretches and channels. The total area of the water surface, according to the State Water Register, is 212 km2, the area of the lake with islands is 250 km2. The average depth of the lake is 5.8 m, the maximum is 24 m. The volume of the contained water is 1.23 km3.
The glacial origin of the lake explains its peculiar shape - it is not a single body of water, but a chain of lakes stretching from north to south for 100 km and interconnected by short narrow channels. The Seliger lake system includes 24 stretches and lakes, interconnected by short straits-intercurrents and long straits-rivers.
The coastline of the lake is more than 500 km long and is significantly indented. The shores are low, sandy in places, there are many natural beaches. There are also many steep banks, overgrown with pine and spruce.
Ice sets on the entire lake by the end of November - early December and lasts until the end of April. In summer, the lake water heats up quickly, already in June the temperature of the upper layer reaches 20 ° C, and in July and the first half of August it warms up to 25 ° C.
The water is fresh, slightly mineralized. Transparency up to 5 m.
