The water and substrate properties in the vegetation zones characteristic of the late stages of lake overgrowth were determined. It was demonstrated that the spatial distirbution of plant communities conformed with the spatial gradient of habitat conditions. With regard to water properties the largest differences between the zones were found in Mg2+, Ca2+, electrolytic conductivity and NH4+. In the case of substrate the zones differed in Ca2+, total Fe and organic matter content. The process of dystrophy proceeded from the terrestrialized peripheral parts of the lake to the centre
