In Kazan, not only spiritual and cultural shrines are revered, but also natural gifts, which are given special attention. On the territory of the city there is an amazing beauty reserve, the Central object of which is the system of lakes "Blue lakes". In 1972 they declared a natural monument and since 1994 have strengthened the status to protected.
The peculiarity of Kazan reservoirs is their transparency, reaching a depth of 35-40 meters. Because of the high concentration of salt, fish is no longer found here, although many years ago in the lakes was found pike. To get to the transport directly to the lakes is impossible, and it is necessary to prepare for long walks on the glades and slopes.
The reserved complex of reservoirs consists of three lakes: Big Blue, Small Blue and Flowing, each of which can be called an Autonomous organism as their channels do not connect. Lakes are enriched with groundwater. The banks are covered with thick reeds. At the bottom of the ponds settled limestone rocks with healing clay, which is in great demand during various medical and cosmetic procedures. Curative mud are no less in demand, but have not a very pleasant smell of rotten eggs due to the high content of hydrogen sulfide in the water.
Blue clay and silt mud give the lake an appropriate noble shade. Throughout the year, their color ranges from azure to dark gray. In fact, the depth here is dangerous, but because of the transparency creates the illusion of shallow water. In this regard, the question of compliance with security rules becomes unconditional. However, the above-mentioned divers depth only beckons. At the bottom there are rare species of plants, small animals – all this can be considered to the smallest detail.
