Mass Death Of Fish with No Reason in Russian Lake

Diving into a deep water will give you a little cool and protecting from heat. But sometimes, going deep into the water is not always a smart idea. One of the good reason is the lake in Siberia has a mass death of fish. this mass death of fish is making more concern to people of Tulagino and none seems to have any ideas at all regarding the death. There is a theory about the dead fish is that it might be killed by removing the ice in the rivers blasted by dynamite in order to prevent flooding in nearby towns but government denied to the cause. For whatever reason it is, but it is never good for the people in Tulagino. This is just a huge waste!
