The Lake of Ryazan and the Ryazan region

Lakes on the territory of the Ryazan region there are 2838 area of over 0.2 hectares. Total area is km2 245,8. Of them 1400 lakes are larger than 1 ha, 1438 — less than 1 ha. Lakes in all districts of the region (see table).

The lake coverage area (the ratio of the area lakes to total land area) is 0,62. A large part of the lakes situated in the floodplains of the Oka, Moksha and Tsna, Great, Pair, Prony and other rivers. All of these lakes 2250. Almost half of them has an area less than 1 ha of This floodplain oxbow lakes. They are formed by moving the channel within the floodplain, in old bends, in varying degrees, have lost touch with the new direction.

These lakes are horseshoe-shaped or sickle-shaped, sometimes they are extended linearly. Width lakes-oxbow lakes is depending on the width of the river, in the floodplain which they are formed, and varies from several meters in the floodplains of small rivers up to the first hundreds of meters on the floodplain of the Oka river. Their length varies respectively from tens of meters up to 1 — 2 km or more, usually naprawiam depth 2-4 m. the largest lakes are ancient lakes situated in the floodplain of the Oka: Velha S., Mormino, Kasari u s, Kazar, there is Petrovicescu at the S. I, Cuman D. Papineau. The length of each of these lakes over 2 km, width — from 60 to 400 m, the area — up to 0.5 km2 or more.

There are more than 340 lakes within the Meshchera lowlands. 130 of them are larger than 1 ha. There are the biggest in the lake area of the Ryazan region (see table).

Among Klepiki, or Great lakes are lake. Oak, Sacred, Kokorevo, Shagara, Ivanovo, Great, Chebukina, Martynova. All of them are interconnected with canals and into the lake system of R. Gov. The water’s edge in the northernmost of the lakes — Oak — 112 m, Martynova the lake from which the river flows … the Great — 111m. Klepiki lakes are located within an extensive hollows, which in the late middle Pleistocene in the era of the Moscow glaciation from the edge of the glacier located to the North of Moscow, was the outflow of melt waters of a glacier. In the late Pleistocene sediments accumulated in the trough of the flow, were partially blurred. On cold days actively developed cryogenic processes, resulting in North of Spas-Klepikov within the trough formed extensive thermokarst depression. South Spas-Klepikov former the trough of the discharge of thawed glacial waters in the early Valdai epoch was filled with lacustrine-alluvial sediments, and to the North in the late Pleistocene formed a wide pond with a mark edge m. It flooded and thermokarst depressions and located between them parts of the surface of the early Valdai accumulation with marks 111 — 117 m. the depth of the lake reached 10 — 15 m, area — 250 km2. Modern lake Ryazan system R. Pry — the remains of this Pleistocene lake. At the end of the late Pleistocene and in the Holocene R. PRA “lowered” the ancient lake. Deep thermokarst basins were filled with organic-mineral silt-sapropel. Filed drilling, power sapropel varies from 0.5 to 9 m and averages 2 m. the Reserves of sapropelic sediments in the lake. Great account for 81 800 thousand m3 in oz. Holy — 21 680 thousand m3.

Distribution of lakes by administrative regions

The largest lakes of the Meshchera lowland

The lake, located on the interfluve of the Oka and PRA (Comhar, NEGAR, Great, Black, Percino,Tasnee, Governoe, etc.), at the confluence of the PRA and the Goose (Holy, Tatar, Urawa, etc.), thermokarst. Their valleys have formed from the thawing of permafrost, which existed here during the late Pleistocene and disappeared in just 10 thousand years ago. All these lakes are small, less than 2 m, depressions have accumulated up to 2 m or more of sapropel, all of them overgrown with the banks.

Several lake basins has karst origin. The most famous of them oz. White D. White. Its depth reaches 45 m (according to other sources, up to 56 m).

Ice cover on the lakes typically occurs in the last ten days of November. Ice thickness in March is 0.5 — 1 m (in cold winters with little snow ). The liberation of the lakes from ice occurs in the second-third decade of April.

In the southern areas of the region almost all lakes are located in floodplains. Lakes on rivers — a rare phenomenon. Typically, this is a small karst lake, for example, S. Voeykova Miloslavska in the area.
