The  lake Planšarsko lake was made by sinking the swampy meadows and then stemming it.  The little lake is protected from the Jezernica with a dam and a reservoir, because this creek can bring a lot of pebbles from the mountains in the flood period. It was meant for tourist purposes only and its highest depth is 2m, the natural habitants are small brown trouts, who migrate upstream in the winter time, when the lake is covered in ice. RD puts in rainbow trouts every year and they grow really fast because the water is rich in. little crustaceans.
