The city where the lake disappeared during Soviet times. The lake went underground

In the Vyaznikovsky district, the forest karst lake Sakantsy near settlement Pivovarovo went underground. A video of a disappeared reservoir, with only silt remaining at the bottom, was published by community "Vyaznikovsky offroad"

“On October 12, 2017, at 1:30 p.m., a failure occurred in the village of Pivovarovo on Lake Sakantsy. All the water went away with the fish." - this caption accompanies the video.

According to the Internet portal telling about the life of the two cities of Vyazniki and Gorokhovets, Yaropolch.ru, the karst lake Sakantsy was located approximately 40 meters from the famous Pivovarovsky failure, formed in 1959. The Pivovarovsky failure itself, according to the testimony of old-timers, is a pit in the middle of the forest, into which a nine-story house could fit. Now the slopes of the failure are overgrown with trees

As explained to Zebra TV by the director of the department of environmental management and environmental protection of the administration Vladimir region Alexey Migachev, it is not surprising that karst sinkholes form in the Vladimir region, especially in the Vyaznikovsky, Gorokhovetsky and Muromsky districts. This is due to the specifics of geological processes in these territories.

“Karst formation is underway. That is, aquifers pass through some rocks containing silt, they are eroded, dissolved and voids are formed. In some places, strata form close to the surface and similar sinkholes are formed. These processes have been going on for decades, with no sudden collapses occurring. And in this place, a void has already formed under this lake, there is about two meters of silt that held water. But, apparently, after the rains these processes became more active, and the silt in some place simply subsided, and the water flowed away like into a funnel.

What will happen to this next - different points of view are expressed. There were cases when these lakes appeared again. The point is that the sinkhole can become silted, and then again it can become a place where water accumulates. But the lake may not recover.

In the Sobinsky district, a lake also went underground about 15 years ago. It stood without water for 5 years, and then filled with water. There was such a story in Gus-Khrustalny. Nobody knows why this happens. Because if you start research, start drilling the surface, the situation may get worse.

Such failures can form anywhere throughout the entire territory, especially in the Vyaznikovsky, Gorokhovetsky and Muromsky districts. There is active formation of karsts there,” - Alexey Migachev explained to Zebra TV.

By the way, it was the karst terrain, prone to failures, that was the most powerful argument against the construction of a nuclear power plant near Murom in the Navashinsky district Nizhny Novgorod region. However, this did not prevent the authorities from approving this particular site for the construction of a nuclear power plant.

“According to geologists, karst lakes go underground due to the dissolution of rocks by underground and surface waters. In the case of Lake Sakantsy, the water was retained thanks to the muddy bottom, which played the role of a plug between the lake and the underground river flowing at a depth of 80 m.

In addition to Vyaznikovsky, karst processes cover Kameshkovsky, Kovrovsky, Gorokhovetsky, Muromsky, Selivanovsky, Sudogodsky, Melenkovsky and Gus-Khrustalny districts,” - explained later

In place of the reservoir, only a funnel with a muddy bottom remained.

Experts believe that the water went underground due to voids caused by soil erosion.

We are talking about karst formation, when rocks containing silt pass through aquifers, and then they are washed away, and voids are formed. This sometimes causes such failures, reports the 360 TV channel.

The lake was located near the famous Pivovarovsky failure, which was formed in 1959 and was a hole the size of a nine-story building. Now it is overgrown with trees.

However, environmentalists did not see anything surprising in the failure. Due to the geological features of these places, such failures often occur in the Vyaznikovsky, Murom and Gorokhovetsky regions.

Perhaps the lake will recover, but it is still impossible to say for sure what will happen to the reservoir next.

In the Sobinsky district, a lake also went underground for 15 years. It stood without water for five years, and then filled up again. The same story happened in Gus-Khrustalny. No one can explain these processes. Moreover, he does not undertake to investigate: drilling can only aggravate the situation. Such failures can appear anywhere.

The disappearance of Lake Trostyanoy in the village of Chernorechye frightened the residents. They are afraid that the entire village could fall into the karst void.
Valentina Brovyakova, head of the administration of the rural settlement of Chernorechye, says that the disappearance of Lake Trostyanoy on the outskirts of the village at the end of July greatly frightened the residents of the area.

How can it be? There was a lake and now, one moment - and it’s gone,” she says. - Some kind of mysticism...

Eyewitnesses are horrified

There were few witnesses. Anyone who saw Trostyanoe Lake go underground experienced horror, and this horror was passed on to everyone who listened to the stories of eyewitnesses. Many perceived what was happening as the beginning of an approaching natural disaster or as a bad mystical sign. What a summer: one disaster after another - fires, dried up reservoirs, shortages drinking water. And then the lake, in which they had been fishing and swimming for decades, suddenly disappeared. And this has never happened in the surrounding area, although there are many such small, round, saucer-like lakes around Chernorechye.

When we were children, we went swimming at Trostyanoe,” recalls 40-year-old Ekaterina Nikolaevna, a resident of the village of Chernorechye. - I swam in it, but even then it frightened me with its depth. No one swam to the middle of the lake; they said there was a pool there. I was splashing at the edge, near the shore, looking warily at the dark water in the middle of the reservoir.

Lately, no one has swam in Trostyanoy. It was impossible to approach: the banks were completely overgrown with grass and reeds. But there were crucian carp and crayfish in it, apparently and invisibly. And it was a fisherman's paradise.

Eyewitnesses say that the water of the lake went underground quite suddenly - with a roar and roar, forming a giant whirlpool in the center, rising above the surface of the water in the form of an inverted funnel. Then the funnel changed from being upside down to becoming normal and very large - all the water went into it.

Fortunately, says another resident of the village, Tatyana Mirgorodskaya, none of the fishermen were on the shore at that moment. Because the banks also collapsed with a roar, along with the grass and reeds: everything was pulled into this terrible funnel. If there had been a person, I think he too would have been sucked into the abyss.

When it was all over, at the site of the funnel in the middle of the lake, people saw something similar to a well, the depth of which no one dares to talk about now.

A black, terrible hole has formed... Ten meters deep, I think, no less,” Tatyana continues. - It was an unpleasant, terrible sight...

This black hole gaped frighteningly for several more days in the place where the water of the lake disappeared.

Return of water

There are different mystical versions circulating among people. Along with abnormal heat, the likes of which no one in the province has ever experienced, the sudden disappearance of the lake, according to some residents of the area, promises even greater troubles and almost heralds the beginning of the end of the world.

“Many say so,” says Chernorechye resident Tatyana Mirgorodskaya, “that we have done something wrong before heaven.

And from materialistic explanations, one thing is passed on from mouth to mouth: everything happened because of the builders developing a sand quarry nearby; they, they say, are to blame for everything. They took out all the sand from under the ground for their building materials, and so a void was formed, into which the water from the lake flowed. Based on the principle of communicating vessels. And this also frightens the residents, although not with heavenly punishment, but also with quite terrible consequences.

They destroyed the environment. We are afraid that because of this, one day the entire village, along with its residents, will fall underground into these voids,” says another villager, Oksana Kondratenko. “We haven’t seen anything like this before.” True, the old people say that the lake disappeared once before: it disappeared just as suddenly, something similar happened many years ago. But so long ago that no one can even remember when exactly.

“I don’t think the quarry is to blame,” concludes Valentina Brovyakova. - The quarry is several kilometers from the lake. There is some other reason. Let scientists talk about it. Here we are guessing this way and that, but in reality no one knows where the lake went and where it is now returning from...

The lake is indeed coming back. His cup is already half full. The water left quickly and noisily, but returned quietly, slowly.

“I think there is only one explanation for this,” says Samara resident Alexey Nikolaevich, who built a dacha in the area of the village of Chernorechye. - Under the village, apparently, there are underwater rivers. They become shallow from the heat or dry out completely, leaving voids in their place. The water went into one of these voids. And now recharge has come from somewhere again, and the lake is filling up again.

Dangerous phenomenon

Lake Trostyanoe seems to be one of those called karst, says Sergei Saksonov, Doctor of Sciences, Professor, Head of the Laboratory of the Institute of Ecology of the Volga Basin. - And that well, the so-called ponor, which was formed after the “disappearance” of the lake, confirms this. Karst lakes are fed by groundwater. Largest quantity karst lakes are located in the Sergievsky, Isaklinsky and Kamyshlinsky districts.

The incident in Chernorechye, of course, could have been caused by the heat, which dried up the underwater rivers and streams, continues Sergei Vladimirovich. - Karst fields are a fairly common phenomenon in the Middle Volga region. Karst sinkholes great amount. They have always been here. And this is actually a dangerous phenomenon. It's not just water that can escape into a karst void. Especially if current developers neglect the danger of this phenomenon. In the old days, people never settled in such places. People felt this danger intuitively, with some deep instinct of self-preservation. And they avoided the ghost lakes, which then disappeared and then appeared, also experiencing a mystical fear of them. The largest and most beautiful of these ghost lakes, as well as the most famous disappearing karst lake, since it is surrounded by an incredible number of fantastic legends, is located in the Elgushi tract on Samarskaya Luka.

People say that it periodically disappears, islands disappear and appear in the middle of this lake. And at the moment of its return from the depths of the earth’s bowels, it emits light that reaches the heavens...

Some don't come back

In the Padovskie oxbow lakes one can observe a negative evolution of floodplain reservoirs. The lakes become heavily silted and overgrown with vegetation from the shores and algae from the bottom. Visible to the naked eye: the lakes are surviving last days of its existence.

Lakes Kostylevo and Dubovoe near Alekseevka station are silting up from the heat and dry land. Once upon a time, they were inhabited by perches, pikes, and roaches. Whole families of Samara vacationed on the beautiful banks of Kostylevo. Nowadays it is deserted, the water level has dropped by more than a meter. You can still save this lake. The water in it rises on some days, you need to be able to hold it back and properly block the flow. But there is no one... Dams are being built incorrectly and the shores of Lake Bazhanikha are being destroyed. Environmentalists are sounding the alarm and demanding decisive measures to protect the Padovsky oxbow lakes.

Residents of the village of Nikolichi, Kungur district, Perm region, discovered dried, cracked earth on the site of the forest lake Peshchera. There was neither water nor fish living in this reservoir. There was only a small gap left, leading deeper into the earth. Apparently, Lake Cave flowed there.
Together with a specialist from the Ostashat House of Culture, Olga Kolyvanova, who contacted the editorial office of the local newspaper Iskra, we are driving along a forest road to the disappeared lake. It is a kilometer from Nikolichi.
- A neighbor told me that the lake had disappeared. He says it was still there at the end of April. I went into the forest on May 9, and in its place there was a puddle and a small failure,” says Olga Stanislavovna. - It's creepy. They've been fishing there all their lives. And with a fishing rod and nets. And then suddenly it just disappeared. Why suddenly?
Where did the Cave go?
We go down to the lowland and follow along a small ravine. In the spring, melt water rushes along it and fills the depression, shaped like an elongated comma. Now on the site of Lake Cave there is a large bright spot, a “bottom” cracked in the sun. Judging by its outline, the length of the reservoir reached 80 meters. Near the shore from the side of the forest you can see a small dip and a narrow hole one and a half meters from the surface, through which, apparently, the lake disappeared, dragging all the aquatic fauna with it. About ten kilometers from the disappeared lake there is the entrance to the Zuyatskaya cave, which is considered one of the largest in Perm region. Its length is 1410 meters. It is notable for its underground lake at the entrance and a stream. Some passages are completely flooded. The water level is subject to significant seasonal fluctuations. Maybe the resulting ponor (the place through which the water left) is the entrance to another cave?

Why did the bottom “crack”?
Local residents are speculating. One version is that it was influenced by the earthquake in Sverdlovsk region with a power of 4.1 points at the epicenter, which happened last fall on the night of October 19. Iskra talked about this on October 20 in the article “Tremors”. Judging by statements on social networks, the vibration was felt not only by residents of the Sverdlovsk region, but also of the Perm region. It also shook in Nikolichi. Perhaps this soil vibration led to the formation of a crack at the bottom of the reservoir? Another version is the activities of oil workers. In the neighboring Berezovsky district, oil is being extracted from the ground. Voids are formed.

There are losers all around
The residents' unrest about the disappeared lake is understandable: the villages are located on karst. Sinkholes, as the locals call small karst sinkholes, are a common occurrence here. But the disappearance of an entire lake is a reason to be wary. The only source of water supply for the villages is Lake Lyubimovo. True, it is located on the opposite side of the collapsed lake - three kilometers from Ostashat. About half a kilometer away, Lake Worms went underground about ten years ago. Then the hole was filled with stones and clay. And in the spring the cavity filled with water again. Residents, of course, are concerned whether similar cases of disappearance of miraculous reservoirs will become a pattern. In Ostashaty and Nikolichi, the benefits of civilization include electricity and water supply serviced by the local collective farm. A lopsided 30-meter pipe stuck into the ground is water tower. The pump forces liquid into it from Lake Lyubimovo, then through the water supply network it enters the houses. The village of Nikolichi, which is located on a hill, has had poor water supply since the beginning of the gardening season: there is not enough pressure. In the village itself there are several long-standing karst sinkholes that are filled with precipitation in the spring. The lakes are protected. Periodically cleaned of mud. They don't let livestock in and don't rinse clothes. The water in them, relatively speaking, is for drinking. There are no other sources of drinking water.

A comment
Researcher at the stationary laboratory of the Mining Institute of the Ural Russian Academy of Sciences Natalya Lavrova:
- It’s difficult to draw any conclusions now. The opening of a crack or hole through which water escaped could have occurred either as a result of man-made impact or due to natural causes. I do not rule out that there may be a cave under the lake. We haven't visited the site yet. Over time, the ponor should be covered with clay and earth. After some time the lake may return.

A lake in Tunisia appeared in 1 day. A phenomenon in the desert.
If in our Perm region the lake disappeared in one night, then in Tunisia the lake appeared in one day. Aren't these wonders of nature?

In Tunisia, a lake appeared in the center of the desert. A large expanse of turquoise water appeared in the Tunisian desert in just 1 day, in a place where there was nothing but hot sand. This phenomenon lake was discovered by shepherds. It is believed to be up to 18 meters deep and covers one hectare. Local geologists suspect that the reservoir arose due to seismic activity, perhaps a rupture occurred above the groundwater level, which opened the passage of liquid to the surface of the rock. Hundreds local residents They built a beach and are enjoying this miracle in an area where they have always sweltered from the heat. However, water may contain chemical impurities of phosphates, which can be harmful to human health, but so far this has not stopped anyone.

The Sakantsy forest lake, more than 20 m deep, completely went underground in the Vyaznikovsky district of the Vladimir region.

About the unique natural phenomenon The head of the department told reporters water resources and water use of the regional administration Ivan Shaposhnikov.

He explained that this happened due to karst formation processes taking place in the area.

“As a result of the erosion of the soil, voids were formed into which water went along with the fish. It is still impossible to say what will happen to the lake next.

There is a possibility that the site of the failure will be flooded and the lake will be restored again. Currently, there is only a funnel in place of the lake,” the specialist said.

Shaposhnikov clarified that the lake was located not far from the Pivovarovsky failure, a similar karst sinkhole that formed in 1959.

A sinkhole is a sinkhole of natural origin. A sinkhole occurs when groundwater erodes soil and rocks, causing the ground to fall into the resulting void.
