Key facts
Chorne Velyke carries the highest mineralisation of all the Shatsk lakes and lies effectively on the edge of Shatsk. A canal joins it to Liutsymyr, through which the lake belongs to the eastern cascade.

What to know
Lake in detail
- The highest mineralisation of all the Shatsk lakes at 303 mg/L — the basin cuts deep into chalk deposits.
- A low isthmus separates it from Liutsymyr and a canal joins them; together the lakes form part of the cascade running through Kruhle to Krymne.
- The northern shore is sandy with a laid-out beach; the southern and south-eastern shores are low and boggy.
- The phytoplankton numbers 27 algal species, and in summer the water reaches the point of blooming.
- Sitting effectively within the town of Shatsk, it is easy to reach by road.
- In the commercial catches of 2010–2018, roach (63.0%) and bream (21.3%) dominated.
History
Chronology
- До 1939
Polish engineers connected Chorne Velyke to Liutsymyr and the eastern cascade of lakes through a system of canals.
- 1983
Shatsk National Nature Park is created, and the lake has been protected within it ever since.
- 2000
A renaturalisation project shared with Liutsymyr stabilised the water level, re-wetted the adjoining peatlands and helped spawning grounds recover.
- 2010
The Chinese sleeper, an invasive alien fish, was recorded in this lake for the first time within Shatsk National Nature Park.
State and recreation
The lake today
Recreation
Beaches: the sandy northern shore, with a pier, volleyball court and gazebos
Known among anglers for the variety of its fish; fishing under the rules of Shatsk National Nature Park.
Ecological pressures
Wastewater from Shatsk
Domestic wastewater from the town enters the northern part, bringing summer blooms and overgrowth of the shoreline.

Hydrology
Hydrological connections
The Shatsk lakes are not isolated bodies of water but a connected network. Canals cut between the late nineteenth and the mid twentieth century, along with natural channels, redistribute water between the lakes and the rivers.
Canal
Lake Liutsymyr
An artificial canal across the low isthmus; Chorne Velyke is the western link of the eastern cascade.
