One of the largest lakes in Europe, located in the Republic of Karelia and the Leningrad region, is Ladoga. On the shores of the lake there are a number of settlements, including Shlisselburg, Novaya Ladoga and Priozersk - in the Leningrad region and Pitkyaranta, Lakhdenpokhya and Sortavala - in the Republic of Karelia. Historians claim that the name of the lake was given by the river that now flows into it. A city of the same name appeared on this river and then the name migrated to the lake. Words with similar pronunciation are found in Karelian and Finnish languages. Among the inhabitants of Karelia this word meant a wave, among the Finns it meant a river in the lowlands.
Ladoga Map
All scientists who have studied the nature of the lake are of the same opinion that the lake is of glacial-tectonic origin, as a result of the rise of land and the retreat of the glacier. Climatic conditions on the lake changing from temperate continental to temperate marine.
The total area occupied by the waters of the lake without taking into account the islands is 17.6 thousand km², and if the islands are taken into account, then 18.1 thousand km². Its length reaches 219 km, and its maximum width is 138 km. The total volume of the lake's water resources is about 908 km³. The topography of the lake bottom is quite varied. It is characterized by an increase in depth in the direction from south to north. This change occurs quite unevenly; if in the northern part the depths range from 70 to 230 meters, then in the south it is only from 20 to 70 meters. The average depth on the lake is considered to be 50 meters, and the maximum is located in the northern part of Lake Valaam and is 233 meters.
Perimeter coastline The lakes are close to 1000 km. The northern shores are mostly high and rocky, heavily indented in places; they form a large number of bays and peninsulas. Southern Shores quite low, there are many shallows and rocky reefs. In addition, the three largest bays on Ladoga are located here - the Volkhovskaya, Svirskaya and Shlisselbrugskaya bays. The eastern shores are little indented, there are only two bays - Uksunlahti and Lunkulanlahti, almost this entire part of the coast is fenced off from the center of the lake by the most big lake, called Mantsinsaari. In this part of the lake you can find few, but quite wide sandy beaches. The western bank is almost entirely covered with bushes and mixed forest, which almost approaches the water. Here you can often find dangerous underwater shallows.
In total, about 35 rivers flow into Ladoga. The largest of them is Svir, it connects Ladoga with another large lake- Onega. The only river flowing out of the lake is called the Neva.
There are about 660 islands on the lake, their total area is more than 1 hectare. Of these, about 500 are concentrated in the northern part of the lake. The largest are Riekkalansari, Mantsinsaari, Kilpola and Tulolansari.
In Lake Ladoga, scientists counted about 120 species of higher aquatic plants, 378 species and subspecies of planktonic animals and 256 species of birds. There are 53 species and varieties of fish here, which go into the rivers to spawn. The most prominent representatives underwater world The lakes are Ladoga slingshot, salmon, farel, whitefish, smelt, vendace, bream, catfish and pike perch.

Europe is famous for its beauty and attractiveness. Its nature has more than once become the property of songs and legends, fairy tales and poems, essays and stories. Among all the diversity, water spaces stand out. Lake Ladoga is a bright representative. Its main difference from other water bodies is the rich flora and fauna.
general characteristics
Lake Ladoga is called the largest in all of Europe. Its area exceeds 18 thousand square kilometers. It is interesting that 457 kilometers of water area are occupied by the islands of Lake Ladoga, which in themselves are not so large. For example, the area of the largest land areas located in the middle of the lake surface does not exceed one hectare. And in total there are more than 650 of them. Nature has placed the islands so that over 500 of them are located in the northwestern part of the lake.
The rocky islands have a bizarre shape and unusual outlines. Their height is 60-70 meters. It is especially interesting to observe the harmonious combination of coastline and island lines. The islands are separated from each other by numerous bays that cut into land areas.
Mother Nature has been working on the artistic and aesthetic design of this corner for thousands of years. globe. Lake Ladoga is one of the oldest water bodies. In its lifetime, it has seen a lot and experienced amazing events, which can be judged by the numerous remnants and remains on its banks and bottom.
New research has made it possible to find out more accurate parameters of the water body. Lake Ladoga stretches 83 kilometers wide and 219 kilometers long. Without the island territory, it occupies a total of 17,578 square kilometers, which allows us to call it the largest European lake.
The length of the coastline exceeds one and a half thousand kilometers. Scientists were able to calculate the coefficient of its ruggedness. It is 2.1, which suggests the presence of multiple bays. The bowl of the lake is distinguished by its impressive capacity, which is 908 cubic kilometers.
Lake depth
The average depth of Lake Ladoga is 51 meters. However, if we talk about the largest, the figure already grows to 230 meters. The depth map of Lake Ladoga also shows impressive indicators. It usually marks the areas that are considered the deepest.
The bottom topography is heterogeneous. Therefore, it is not surprising that the depth of Lake Ladoga varies throughout its entire water area. For example, in the southern part the bottom is flat and smooth. This helps reduce the depth. The decrease is observed from north to south. In the northern part, the depth reaches 10-100 meters, and in the southern part this value is an order of magnitude lower and varies in the range from 3 to 7 meters. The bottom is distinguished by rocky spits and shallows, and you can even find clusters of boulders.
Bottom relief
In general, such differences in depth are explained by the peculiarities of the geological structure of the bottom. Which, in turn, is due to its impressive length. Geological structure also leaves its mark on the lake basin and its appearance. Interestingly, the bottom topography seems to resemble islands. He copies them exactly. Thus, at the bottom of the lake you can observe mountains and plains, depressions and potholes, hills and slopes.
Depressions up to 100 meters deep most often predominate. There are more than 500 of them in the northwestern part of the lake. Interestingly, such formations are concentrated in groups. And they, in turn, create a kind of labyrinth of bays. This phenomenon is called skerry. The depth map of Lake Ladoga allows you to verify this.
The slope of the lake has an average of 0.0105, and the angle averages 0.35 degrees. This value near the northern coast is already 1.52 degrees, and near the eastern coast it is 0.03. This is also considered a fairly important indicator.
Animal world
In a country like Russia, Lake Ladoga plays a huge role. It is called the supplier of drinking water for the northern capital of the state - St. Petersburg. However, in addition to this, Ladoga is home to a huge number of different animals. The main place among them, of course, is occupied by fish.
Today, more than 58 varieties and species of fish are known to exist in the waves of Lake Ladoga. It is interesting that there are also those who are “guests” in Ladoga. These include conger eel, Baltic salmon and sturgeon. They only occasionally swim into the waters of the lake. Their permanent habitat is The Gulf of Finland and Baltic.
Unfortunately, due to the massive fishing of fish today, not all of its former inhabitants remain alive in Ladoga. Sometimes representatives of the fish kingdom disappear for no apparent reason. For example, sterlet. It no longer occurs in Ladoga waters, and researchers have never discovered the reason for this.
New species
But new inhabitants appeared in the lake. They are represented by peled and carp. The latter appeared in Ladoga relatively recently - in 1952-1953. The reason for this was that it was bred in the nearby Lake Ilmen. The fate of the peled was similar. It “wandered” to Ladoga from the Karelian Isthmus, where they began actively breeding it in the late 50s of the last century.
In addition, in the waters you can also find such fish as palia, salmon, pike perch, whitefish, bream, trout, ripus and vendace. They are distinguished by their value in the field of industry. These species are called commercial. There are also less valuable inhabitants of the lake. Among them are roach, smelt, pike, ruffe, blue bream, bleak and silver bream. They are considered no less tasty, but their use in food is represented in smaller quantities.
It is probably impossible to really name all the fish that are found in the waters of Lake Ladoga. There are so many inhabitants there that work to discover and study them continues to this day.
On the verge of extinction
Some fish of Lake Ladoga are now on the verge of extinction. Among them there are those that are considered valuable in the industrial field. The clearest example is salmon. In Ladoga there are individuals whose weight exceeds 10 kilograms. They are real giants. Interestingly, the fish go to spawn in late spring and summer. The young live there for no more than a couple of years, and then return to the lake.
The rivers are now clogged with lumber, making it difficult for salmon to spawn. In this regard, it was decided to suspend mass fishing. The corresponding law was passed back in 1960.
Another valuable fish is palia. She lives in the northern part of the lake. In winter it can be found at a depth of more than 70 meters, and in the warm months it rises to 20-30. Reproduction occurs in mid-autumn.
Whitefish also live in Ladoga. Now there are seven varieties of them in the lake. Four of them, namely lake Ladoga, Ludog, black and Valaam, are considered exclusively riverine, and the other three - Svir, Vuoksa and Volkhov - can live both in the lake and in the river. On average, during the breeding season, each individual lays about nine thousand eggs in October and November.
Just recently, people were massively engaged in catching whitefish, but now this species is on the verge of extinction. A peculiar reason for this can be called the construction of the Volkhov hydroelectric power station dam. Pisces were unable to overcome such an obstacle, and the measures people took to achieve this did not save the situation.
Rivers of Lake Ladoga
Now let's talk about waterways.
The rivers of Lake Ladoga are very numerous. This allows us to talk about its wide drainage basin. Its area exceeds 250 thousand square kilometers. Not every lake can boast such figures.
Finland and Karelia, located nearby, share water resources with Ladoga; rivers also carry their waves from the Novgorod, Pskov and Vologda lands. The water bodies of the Arkhangelsk and Leningrad regions make their contribution.
In total, about 45 thousand streams and rivers flow into Lake Ladoga. It is interesting that before becoming part of Ladoga, river waters accumulate in nearby lakes, including Saimaa, Onega and Ilmen. They, in turn, allow the formation of such tributaries of the main Ladoga as the Volkhova, Vuokse and Svir. In total, they bring more than 57 cubic kilometers of water into the lake per year. This represents approximately 85 percent of the total water mass that accumulates in the area we are considering. geographical object in a year.
All other tributaries are called small. There is no explanation for this, because among them there are such impressive deep rivers as Janisjoki, Syas and Tulemajoki.
It should be understood that the tributaries of the Ladoga are quite young - by the standards of rivers - in age. They are only 10-12 thousand years old. That is why most of them have not yet formed wide valleys. They flow among rocky areas and steep banks.
The Baltic crystalline shield lies in the northeastern part of the lake. That is why the deepest and loudest tributaries flow into Ladoga from that side. Very often they turn into full-flowing stormy streams, encountering rocks on their way that are quite difficult to erode.
Tributary Svir
Lake Ladoga is located in Russia, and its deepest stream is called the Svir. This river flows from the Svirskaya Bay of Lake Onega, and flows into Ladoga from the southeast.
Its length is about 224 kilometers. The river includes two large tributaries, which are named Pasha and Oyat. It is interesting that the origin of this object is still covered in secrets and mysteries.
The Svir River itself and its banks are not distinguished by the picturesqueness inherent in Ladoga. The description of Lake Ladoga tells about the amazing beauty of its shores, which Svir cannot boast of. Its coastline is covered with alder bushes and marshy plants, and there are coniferous forests. Basically, the banks of the Svir River are accumulations of stones and boulders.
In ancient times, Svir was famous for its numerous rapids. They could not be called high, but the piles of boulders presented a serious obstacle to navigation. Locals very often they rescued sailors, helping them cope with crossings. Very often, residents of coastal villages and towns themselves served as sailors, pilots and even captains. The proximity to a deep river left its mark on the character and way of life of the people.
But if we talk about the animal world, it is quite large. It is in the waters of this river that salmon spawning is often observed. In spring you can find schools of these fish heading to the mouth of the Svir. The tributaries Oyat and Pasha play the main role in spawning. Ichthyologists believe that it is these rivers that can contribute to the revival of salmon in Lake Ladoga.
When to visit
Over its centuries-old history, Lake Ladoga has been shrouded in secrets, riddles and legends. All this, of course, attracts numerous tourists. People also travel to Ladoga to admire the amazing beauty of nature and see with their own eyes one of the largest lakes in the world.
In order not to make a mistake, you should know when it is better to go and what time to give preference.
A trip here in May and June will be foggy in the truest sense of the word. At the end of May and beginning of June, thick fogs descend on Ladoga, in which it is quite easy to get lost. In such cases, it is very important to take experienced guides with you who will help you get on the right path and see all the surrounding beauty.
This time is considered quite cold for those places. In the evening, the skerries can be covered with a thin crust of ice, and the wind brings dampness. Of particular interest are the few hours after sunny weather. At such moments, the lake shines with calm and attractiveness. However, the very next moment a breeze blows in. It causes meter-long waves in the bays, although the lake off the coast continues to be peaceful.
One of the most striking advantages of this time, of course, after the attractive appearance of the coastal area, is the complete absence of mosquitoes. The extraordinary cleanliness of the lake is also called a virtue. The bottom, even at a depth of several meters, can be seen extremely clearly. It is believed that if you drink water at such a moment, happiness will not take long to arrive. The water itself is clean and tasty.
Those people who value comfort and coziness should visit Ladoga in the last two months of summer. This period is considered the best for proper rest. In this case, the air and water temperatures exceed the optimal mark, allowing you to swim in the waves of the lake and sunbathe on the shore. On the islands you can pick berries and mushrooms, which are abundant there.
Those people who travel to Ladoga with the aim of admiring the local beauty should choose the autumn months, when literally the entire coast shimmers with gold and bronze. In October, the weather worsens, accompanied by fog and storms. At such times you can meet many artists and landscape painters here. They try to capture the lush beauty of Ladoga.
Lake Ladoga in winter also presents an interesting sight. However, it is quite cold here at this time of year. But the middle of the lake does not freeze even in severe frosts due to its impressive depth.
Those people who want to visit this corner of our vast Motherland should look for Lake Ladoga on the map. Many travel companies offer entire routes. If you wish, you can choose one of the proposed ones or create your own.
A trip to the coast of Lake Ladoga will surely be memorable for everyone. This area is distinguished by the amazing beauty of nature at any time of the year, the diversity of flora and fauna, as well as the opportunity to have a great rest.
