The Lake Ontario.
Lake Ontario is one of the five Great lakes of North America. It is the lowermost and is the smallest of them. From the North and the South-West, it is bounded by the canadian province of Ontario, and from the South American state of new York. Ontario, the most populous of all the provinces of Canada, is named after lake Ontario. In the language of the Indian tribe Huron ontario means ” Lake of shining waters”. It is the latest in the chain of the Great lakes and serves as an outlet to the Atlantic ocean via river St. Lawrence. In the lake empties into the river Niagara,which connects lake Ontario with lake Erie, and the river flows out of St. Lawrence river, which flows into the Atlantic ocean. Lake Ontario is the easternmost of the Great lakes, and has the smallest area of water space is about 19,000 square km of Navigable canals connects lake Ontario with lake Erie and the Hudson river, to the waters of the lake adjacent to the famous lake – toes pertaining to typical tunnel valleys.*
At various times lake Ontario had different names, on the maps of 1662-1663.g. the lake was called Ongiara (Ondiara), and on French maps, 1912. it was called Frontenac (Frontenac Lac). In size, the lake occupies the 14th place in the world. The length of the coastline is 1146 km, a maximum depth of 244 m, a mean depth of 86 m. the length of the lake – cm, width – 85km, the volume of water is 1640 cubic km. the Lake is situated at an altitude of 75 m above sea level.

Lake Ontario, like the other four lakes within the Great lakes system, is located in the industrial area of Canada and the U.S., due to intensive human activities, the ecology of the Great lakes was broken, water in the lakes was contaminated with heavy metals, organic elements, toxic substances. In 50-ies of XX century.USA and Canada(Ontario) has developed joint activities to improve the ecology of the Great lakes: the reduction of harmful discharges from the industrial enterprises in lake water (detergents containing phosphorus, sewage, petroleum products). Were created by domestic and bilateral programmes on water purification in lakes and to control possible sources of pollution created by the legislative framework. There has been impressive results in reducing the ingress of harmful substances into the water of the lakes. The lake water quality has improved significantly, which contributed actively to the revival of the surrounding flora and fauna.
The shallows at the entrance to the bays formed by the constantly blowing in one direction winds and currents create a large number of lagoons and deep harbors such as the Harbor in Toronto and in Hamilton. Choose a sandbank,which separates the small inlets from the lake, creating wonderful beaches. These shallows, connecting with the swampy lowlands, create a comfortable backwaters where birds feel safe in the shallows and fine trees and shrubs, and inhabited by the mass of animals.
The lake is of glacial origin. Above-mentioned lake, adjacent to lake Ontario that are typical of tunnel valleys, i.e., valleys formed by the movement of the glacier, as the ice would cut through soft rock, and during the melting of the glacier, they were filled with water.
Around the lake many deciduous forests consisting of oak, maple, beech, Linden, ash.meet pine, spruce, fir, and juniper,in the glades there is a lot of mushrooms, and on flood plains – grass, a lot of cornflowers, dandelions, milkweed.
Lake Ontario is rich with fish, it is home to whitefish, burbot, perch, goby, various species of salmon, sturgeon. The sturgeon population has decreased significantly due to contamination of the lake water. Now lake sturgeon is very rare, however, taken measures to increase its population. Lakes always have a great influence on climate, lake Ontario is no exception. We, living in Toronto, feel “breath” of the lake: the weather changes instantly. Just now the sun was shining, and the sky was covered with clouds. Lake Ontario is quite deep, so it rarely freezes in winter completely. Ice cover can range from 10 to 90% of the lake surface, depending on winter severity. Most often, ice forms along the shoreline and in shallow backwaters and lagoons. In cold weather, the wind, passing over the warmer water pick up moisture, which then falls as snow. This so-called lake – effect snow.Given the prevailing winter winds, North-Western, southern and South-Eastern shoreline of the lake called “snow belt” (snowbelt).East of lake Ontario is a place called Tug Hill Plateau, where it creates ideal conditions for lake-effect snow. Here in winter you can go skiing, and snowboarders have a place to turn. The water level in the lake fluctuates. To a special kind of level fluctuations are seiches. Seiches or standing waves are rapid fluctuations that are close to periodic, when in one part of the lake level rises, and the opposite side is lowered, thus swinging the entire mass of water to the bottom, trying to regain his balance, she brought some external influences: wind, sudden changes in atmospheric pressure or seismic disturbances. Casseopaya oscillations are generated and wind – tide phenomena, creating a difference of levels at opposite ends of the lake. Of seiches – rhythm of lake Ontario is 11 minutes, typically the seiche effect is set to 2 cm, but it can be considerably enhanced as a result of wave interference, caused by various external influences. Here is a description of the seiche effect on lake Michigan, by an eye-witness of this phenomenon Laura Lee:
This is such a complex system is a remarkably beautiful lake Ontario.

At any time of the year the lake is very beautiful. In different bays water has a different color: from grey to bright blue, the lake resembles the sea to the horizon is water, water, splashing, rolling stones, and the sea roars the surf.
