The Poraj Lake is a water reservoir in the commune of Poraj, not far from Częstochowa. It was created by damming the Warta river in the 70s of the twentieth century. It is a picturesque water body that has already blended in with the surrounding landscape. That is why, there are numerous cottages built around it. The lake also attracts anglers. However, bathing and swimming have been recently banned due to the water pollution.
