Osredek was a hamlet of Križevec until 1994, when it was administratively separated and became a village in its own right named Osredek. In 1998, it was renamed Osredek pri Zrečah (literally, 'Osredek near Zreče').[3]
Lake Zreče
Lake Zreče (Slovene: Zreško jezero) lies within the territory of the settlement. Lake Zreče is a reservoir that was created in 2000 by damming Koprivnica Creek, a right tributary of the Dravinja River. The reservoir has two parts; the lower part of the reservoir is 700 m long with an area of 13,500 m², and the upper part is 300 m long with an area of 2,500 m². The upper part is used as a spawning ground. The reservoir is 8 m deep at its deepest point.[4]
