The river from Achensee to Isar is called Seeache or Ache in Austria and Walchen in Germany . In Bavarian maps the name of the Tyrolean river section is indicated with Achenbach . The course of the river in the northern half of the Achental loops around the northeast corner of the Karwendel Mountains, separating it from the Mangfall Mountains . As a lake it is the natural outflow of the Achensee . It leaves the lake at the northern end and drains the northern Achental near Achenkirch . Since the construction of the Achensee power plant in the Inn Valley , however, a large part of the Achensee water has flowed into the Inn . Near the Kaiserwacht at the Achenpass , the river turns increasingly west. As Walchen he reaches the Isar through the Walchenklamm . The natural mouth has sunk in the Sylvenstein reservoir since the late 1950s .

The Ache is classified in water quality class II.

     Despite intensive efforts, no uniform solution has yet been achieved. "
   • Federal Office for Metrology and Surveying (BEV), Department 14: “According to information from Mr. Pockstaller (Head of the Achenkirch municipal office), only the name Seeache is used locally. Therefore this name can also be found on our menu.
     The hydrographic portal of the Federal Ministry of Agriculture and Forestry is not meaningful, because we used an earlier name there at some point and not updated later. "
