geography
course
It rises in Baldeggersee , which is fed by several short streams next to the Ron . At Mosen the stream flows into the Hallwilersee . It emerges from the lake again between Boniswil and Seengen . Hallwyl Castle , one of the most important moated castles in Switzerland , is located around 700 meters from the northern end of the lake on two artificial islands . On the southern outskirts of Lenzburg , an underground relief tunnel branches off, which meets the brook again below Niederlenz ; The excess amount of water is channeled through this during flooding. The Aabach flows into the Aare in Wildegg , shortly after the Bünz flows into the Aabach almost two hundred meters before it.
