The reservoir was created by flooding the excavations of the Kuźnica Warężyńska sand mine.
It is the deepest of the four Pogoria reservoirs, with certain sections reaching significant depths due to the former mining activity.
The reservoir acts as a crucial dry polder for the Brynica river to manage overflow during periods of high rainfall.
A portion of the shoreline is strictly protected to prevent erosion and ensure the structural integrity of the dam embankments.
Zbiornik Kuźnica Warężyńska, commonly known as Pogoria IV, is an artificial water reservoir located in the Dąbrowa Górnicza area near Sosnowiec. Created by flooding former sand excavation pits, it is the largest of the four Pogoria lakes, covering approximately 560 hectares. The reservoir functions primarily as a flood control basin for the Brynica river and serves as a significant regional site for water recreation. The perimeter is characterized by a mix of concrete embankments and sandy shorelines, though much of the shoreline remains fenced due to ongoing safety restrictions. Despite its size, the lake lacks the extensive commercial infrastructure found at the adjacent Pogoria III. It is a critical habitat for migratory birds, particularly during spring and autumn seasons.

Stick to the marked asphalt perimeter paths, as off-trail areas near the water can be muddy or restricted by fencing.
Bring your own supplies, as food kiosks and facilities are extremely sparse compared to the neighboring lakes.
Cyclists should prepare for a long, flat route around the reservoir, which is popular for endurance training.
Attempting to swim in areas marked with prohibition signs, as the depth changes abruptly and some zones are strictly off-limits for safety.
