Extreme overgrowth
Agricultural run-off and the drainage-driven fall in water level accelerate eutrophication, the build-up of sapropel and the lake's conversion into a bog.

Key facts
Plotychchia is a very shallow link of the flow-through cascade between Dovhe and Krymne. The lake is overgrowing rapidly, and the sapropel accumulated in it exceeds its water volume tenfold.

What to know
Lake in detail
- Part of the flow-through cascade Liutsymyr–Kruhle–Dovhe–Plotychchia–Krymne.
- In a stage of rapid overgrowth: it holds 549,000 m³ of sapropel against a water volume of only 54,900 m³.
- The name probably comes from its dominant fish, the roach.
- The degradation is driven by mineral fertiliser washed off arable land and by the drop in water level caused by drainage works.
- The official water-management profile attests roach, perch, pike, crucian carp and tench directly.
- The name “crucian carp” is not resolved to a species, so it is matched to the native crucian carp only with moderate confidence.
