Excerpt: The Walchensee Power Plant is a high pressure storage power station in Bavaria. With an installed output of 124 MW it is today one the largest of its kind in Germany. It is located near Kochel (distance the town of Walchensee about 14 km). Changing of the Pelton wheels The storage power station uses the natural downward gradient of about 200 m between Walchensee, serving as an "upper reservoir" (802 m ue. NN), and the "lower reservoir" of Kochelsee (599 m ue. NN) to generate electricity. Through six 450 meters (approx.) long pipes, which connect the two natural "basins," the water flows to the turbines of this hydro-electric power plant: four Pelton and four Francis water turbines. Subsequently, it is directed into Lake Kochel. Due to the strongly varying water levels, neither lake properly freezes in the winter. The ice in each of the bays is only very thin and may not be walked upon. The natural outflow of Lake Walchen at Niedernach - over the Jachen to the Isar - is blocked by a weir, yet the natural inflow to the lake is not sufficient to provide enough water for the operation of the storage power station. Therefore the water of the Isar and Ri bach is used. The Isar, which flow as a whitewater river from the Austrian part of the Karwendel mountains, is dammed between Mittenwald and Kr n at river-kilometer 251.5 by a weir, there forms the Kruener Isar reservoir (870m) and is nearly completely directed to Lake Walchen. This Isarwasser flows first after passing the run hydro-electric power plant Kruen in an open channel, crosses before barrier gau by means of a Duekers the federal highway 11 and with barrier...More: http: //booksllc.net/?id=1428476
