The reservoir serves as an important site for over 200 bird species, many of which are endangered or rare.
The dam at Jeziorsko is equipped with a hydroelectric power plant that has been operational since the late 1980s.
The reservoir was created by flooding several villages, remnants of which remain submerged.
During low water levels, mudflats emerge that are critical for the survival of migratory waders.
The reservoir is part of the 'Natura 2000' network, highlighting its European ecological significance.
It is a frequent training ground for regional sailing clubs due to its wide, open expanse.
Jeziorsko is the largest retention reservoir in the Łódź Voivodeship, covering approximately 42 square kilometers on the Warta River. Constructed between 1975 and 1986, it serves primarily as a flood control measure for the Warta River valley. The reservoir features a dam structure in its northern section near Skęczniew. A significant portion of the reservoir and its surrounding wetlands form the Jeziorsko Ornithological Reserve, established to protect migratory bird habitats. The area is a key stopover for waterfowl, including cranes, herons, and various species of ducks. Water sports, including sailing and windsurfing, are popular on the main basin. Fishing is permitted in designated zones, subject to regional angling regulations. The reservoir's water levels fluctuate significantly depending on seasonal precipitation and flood management requirements.
The observation deck near the Skęczniew dam provides a panoramic view of the main reservoir basin.
Bring binoculars if you are interested in birdwatching, as the best viewpoints are often at a distance from nesting sites.
Check local water level reports before planning water sports, as the reservoir depth can vary significantly.
Use insect repellent, as the marshy areas near the shoreline can have high mosquito activity in summer.
Do not attempt to swim or sail in areas designated as nature reserves, as these are protected zones.
Stay on designated paths in the ornithological reserve to avoid disturbing nesting birds; keep noise levels low in conservation zones.
