Sissle

The Sissle is a 16-kilometre (10 mi) long <a href="/facts/River/GP7MSur6">river</a> in the <a href="/facts/Switzerland/LcGuxeTe">Swiss</a> canton of <a href="/facts/Aargau/89uQz1xQ">Aargau</a> in Switzerland. It is a tributary of the <a href="/facts/Rhine/MgJ88oaz">Rhine</a> and drains the eastern part of the <a href="/facts/Fricktal/tvMfmJvt">Fricktal</a>. The largest town on the river is <a href="/facts/Frick_AG/7oDD36pa">Frick</a>.
The river rises in the municipalities of <a href="/facts/Schinznach-Dorf/UxvyGvaH">Schinznach-Dorf</a> and <a href="/facts/Thalheim_AG/7pRhpLbk">Thalheim</a> at an elevation of 650 metres (2,130 ft) above sea level on the southern slope of Mount Dreierberg and the northern slope of Mount Zeiher Homberg, in the <a href="/facts/Jura_Mountains/8x0AMMft">Jura Mountains</a>. Shortly after the source, the river breaks through a <a href="/facts/Water_gap/xlURkQrw">water gap</a> between the Dreierberg mountain and the Zeiher Homberg and then falls off rapidly. It passed the Talmatt and delimits the district Iberg of the municipality of Zeihen. After about 2.5 kilometres (1.6 mi), the Sissle flows past <a href="/facts/Effingen/a6AKBycy">Effingen</a> railway station and the west portal of the <a href="/facts/B%25C3%25B6zberg_railway_tunnel/TbbrxB3z">Bözberg railway tunnel</a>, at an elevation of about 450 metres (1,480 ft). The river had to be canalized here when the railway was constructed.
From here on, the landscape is fairly flat and the river follows the <a href="/facts/A3_motorway_(Switzerland)/AWGtLBwr">A3</a> motorway. It flows freely until <a href="/facts/Hornussen_AG/D391pgqQ">Hornussen</a> and is then canalized until <a href="/facts/Eiken%2c_Switzerland/XBv29Sck">Eiken</a>, where it changes direction from northwest to north, and enters the Rhine valley. It receives the left tributary Bruggbach, coming from <a href="/facts/Wittnau/vjkatDtj">Wittnau</a>. The last 2.5 kilometres (1.6 mi) of the Sissle <a href="/facts/Meander/XIGCmCq9">meander</a> strongly. It ends at the village of <a href="/facts/Sisseln/m18oG3v7">Sisseln</a>, where it flows into the <a href="/facts/High_Rhine/415f2YL2">High Rhine</a> at an elevation of 290 metres (950 ft).
