The place where the Łyna River flows from Lake Ustrych is separated by a small hydroelectric power plant. This point is called the Ustrych Power Plant. The power plant itself is maintenance-free and the water damming height is about 1 m. The water moves two small power turbines, which are secured with three bulkheads.

very nice views of the lake (the road runs on a slope several meters above). A bit sandy in places and uphill, but on a tourist bike it will do.

A smooth gravel road leads to this place from the east from Orłowo. The road from the parking place in the west is cobbled. In either direction, you decent to this place and then you have to climb out.

A small souvenir shop & cafe and a toilet. A good place to lock and leave your bicycle and walk to Źródła Łyny (Łyna Springs) nature reserve.
