Karelian Isthmus lakes located nearly to Saint Petersburg megapolis experience constantly growing anthropogenic influence due to intensive economic activity and recreation. Complex assessment of ecological state of 50 Karelian Isthmus lakes situated in different parts of the region in July of 2009-2013 revealed noticeable transformations of their ecosystems. Lakes of northern part of the Karelian Isthmus situated at the Baltic crystalline shield undergo minimum transformation but even here many lakes became mesotrophic or slightly eutrophic. Lakes of the Gulf of Finland basin situated in the resort zone are the most eutrophied. Increase of nutrient loading to water-bodies, results in growth of phytoplankton biomass and decrease of biodiversity
