Writes Kharitonov Mikhail (mmkharitonov) :
I fed to the question of the height of the reservoir - Krymsk is more than 100 meters below the Neberjaevsky reservoir (the picture was taken from @timurkhorev).

Here http://www.new-kuban.ru/16.01.02/kx21g002.html , in 2002, it is said that "if the dam is broken, the stream will simply demolish the village of Neberjaevsky and the city of Crimean, which will be on its way, as dozens or even hundreds of people may die. The Nesberdzhaevsky reservoir cannot be drained according to the usual scheme, because the lower drain of the “smart” initiative is flooded with concrete, and the emergency water supply simply can’t cope with the huge amount of melt water, and it can be clogged with the ice that is now covered with the reservoir and the emergency, where Valery Nikolayevich Nesterenko was addressed with his proposal for water description, even refused to open water. Listen: "We have a lot of work."
We continue further:
Here http://www.novorab.ru/articleSection/details/2129 states that since 1999 only a project for the reconstruction of the reservoir has been developed, no significant work has been carried out.
Here http://www.nnvrsk.ru/?article=4954 states that 600 million rubles will be required to reconstruct a "launched" reservoir.
There is an interview with the employee and photos that also characterize the "neglect" http://novo-city.ru/news/1/27119/s-neba-let-v-krany-ne-popadaet/ .
Even on Tkachev’s website it is said about the same thing - http://www.antkachev.ru/feeds/news/detail.php?element_id=9036 .
Meanwhile, decisions of the competent authorities contradict each other:
1) by the decision of the CCC and the PB of the Administration of the Krasnodar Territory No. 631 dated 03.23.2009 the Neberjaevskoye reservoir is assigned to hydrodynamic potentially dangerous objects.
2) here http://www.novodar.ru/index.php/big-tr-punkt/337-duma-cat/1504-sdotsgsnatmogn-10-2010 The technical condition of the reservoir is recognized as satisfactory.
In its place, everything sets reality-http: //www.rtn-tv.ru/index.php/shows/heroes/1596-4-.html . It says that in Novorossiysk for 4 days they sat without water due to the fact that on June 7, a hydraulic waist occurred on the Neberjaevsky reservoir, which tore off the valves in the Fisanovsky tank. That is, a hydraulic boom caused by spilling rains could lead to the fact that there wasn’t even had to be dropped - the dam could simply break through.
What are we getting? In 2002, the resident, obviously, after the less large -scale flood in the same year, applied to the competent authorities with a warning about the imminent emergency in the future. For 10 years, to prevent danger, it was not made practically or nothing at all!
P.S. The theory about the possibility of the descent of the Barnian reservoir is less likely, in this http://www.kbvu-fgu.ru/bvu7011624 , an official document says that in the summer, on the contrary, they gain water from floods. At the same time, the same fact could also lead to the overflow of the reservoir, which, with the usual level of equipment wear could become fatal.
Update. I made a mistake with the conclusion - the flood in Krymsk was in August 2002, as the sources say in the comments on this post. That is, the authorities have not prevented two water discharges, which makes the situation even more terrible.

PS Regarding the causes of floods. I drove up the rivers of Bakanka and along Neberjay how much I could. He came to the conclusion that the discharge from the Neberjaevsky reservoir could not be the main cause of the flood, although the locals adhere to this version of the events. All the tributaries of Adagum rose, and not just the Neberjei River, on which the reservoir is located.
That is, it is quite logical that the river, whose sources are all, as one, are located on the watersheds http://budetinteeresno.info/tihomirov_13_il.htm , emerged from the coasts during the rains. But the question of why residents remember such rains, but such floods - no, remains open.
