What to know

Lake in detail

One of the few lakes of the group with a glacial rather than karst origin; the basin is irregular and elongated.
A canal brings water from Pulemetske into Ostrivianske, which then feeds the ponds of the Ladanka fish farm; it is also connected to Luky.
The village of Ostrivia sits on the high eastern shore, while the north-western shores are boggy.
Between 1999 and 2003 the park ran projects to renaturalise the adjoining marshes.
A quiet, little-visited lake with wild surroundings, suitable for swimming near Ostrivia.
In the 2010–2018 catches brown bullhead (39.6%), roach (19.1%) and crucian carp (15.5%) dominated; crayfish are still caught here, once a commercial species across the whole system.

History

Chronology

1983
Ostrivianske is taken into Shatsk National Nature Park.
1999–2003
Renaturalisation projects were carried out in the adjoining marshes to restore the natural water regime.
2014–2015
Autumn hydrochemical series determined pH, mineralisation and nitrogen and phosphorus concentrations.
2010–2018
The invasive brown bullhead dominated the commercial catches, and the lake remained one of the places where crayfish were taken.
2021
A morphodynamic comparison showed the area to be relatively stable, but volume estimates to differ widely.

State and recreation

The lake today

Recreation

Beaches: the shores by the village of Ostrivia (eastern shore)

Recreational fishing under the rules of Shatsk National Nature Park, with a closure during spawning. The lake has suffered from poaching in recent years.

How the lake has changed

1933–2021

The area has stayed almost constant or grown slightly, yet volume estimates from different years diverge considerably because of differing methods and mapping bases.

Ecological pressures

Poaching and overgrowth

Illegal fishing, and heavy overgrowth of the silty bed by aquatic vegetation.
