Currently, basin of river Nura is experiencing a critical situation due to pollution of its waters by heavy metals, mineral oil and other chemical products. Sewage waters throughout tens of kilometres along the river annually carry out the pollutants. The polluted water might have reached the lakes of KSNR and presented potential threat for their inhabitants.
Some hydro chemical researches needs to be done in order to get the knowledge to predict the future ecological condition of the lakes. Despite the researchers might lead to re-planting or re-introducing new species of plants or animals, such activities were considered prohibited by local law. The management perceived that altering according to the law about Special Protected Nature Territories, introduction (installation or other kinds of plants and animals) in protected area is strictly forbidden. For this reason, planting or re-planting in reserve should not take place, even though it was in order to maintain the ecosystems.
