[1] Lake Rożnow was created not long before the invasion of Poland, after a dam had been built on the 80th kilometre distance of the Dunajec river.

The shoreline is marked by numerous peninsulas and bays, located at the mouths of several smaller rivers, which flow into the Dunajec.

The lake is surrounded by forested hills, and its picturesque location makes it a very popular tourist center.

The dam was built by a Polish-French company, which constructed a special settlement for the workers and engineers (the so-called French Colony), together with narrow gauge rail line to a stone quarry at Marcinkowice.

Construction was interrupted after the Invasion of Poland, but as early as November 1939, German authorities of the General Government decided to continue it, using Polish plans.
