The lake is a water basin strongly overgrown with small water clarity. It is supplied with small watercourse flowing from the east , and probably partly supplied with underground waters. Formation of the lake was influenced by people. There are permanent marks of humans actions, among others mill's ruins, which functioned for a long time in the first half of XX century. Contemporarily, the lake is maintained thanks to damming water obtained with help of sandbags piled up into dike. The remains of material culture are here the subjects of protection.
