ISAR

(identical with Isere, in Celtic "the rapid"), a river of Bavaria. It rises in the Tirolese Alps, at an altitude of 5,840 feet. It winds in deep, narrow gorges through the Alps, and at Tolz (2,100 ft.), enters the Bavarian plain, which it traverses in a generally north and north-east direction, and enters the Danube immediately below Deggendorf. It is 219 m. long with a drainage

area of 38,200 sq.m. Below Munich the stream is 14o to 35o yd. wide, and is studded with islands. It is not navigable, except for rafts. The Isar is essentially the national stream of the Bavarians; it traverses the finest corn land in the kingdom. On its banks lie the cities of Munich and Landshut, and the venerable episcopal see of Freising. (See DANUBE.)
