The Isar river drains a substantial part of the [[Bavarian Alps]] and parts of the [[Karwendel]] mountains.

Apart from the larger tributaries of [[Loisach]] and [[Amper]], many smaller rivers flow into the Isar. The [[drainage basin]] contains some 9,000 square kilometers (roughly 3,500 square miles). During the winter, most of the [[Precipitation (meteorology)|precipitation]] in the Alps turns into [[snow]]. The [[snowmelt]] can result in an increased water flow down the Isar rivers during the spring meltdown. It has an average [[discharge (hydrology)|discharge]] at the [[River mouth|mouth]] of 174 m<sup>3</sup>/s.

The official source of the Isar is located in the [[Hinterau valley]] east of the village [[Scharnitz]] in the [[Karwendel mountains]] at a height above [[sea level]] of 1160m. The Lavatschbach is the Isar's longest headstream. A further source for the young Isar is the Birkkarbach, which has its sources in the [[Birkkarspitze]] mountain.

The Isar enters [[Upper Bavaria]] after ca. 22&nbsp;km just north of [[Scharnitz]] and the Isar is dammed for the first time between [[Mittenwald]] and [[Krün]]. Some of the Isar waters are channeled via the [[Rißbach]] into the [[Walchensee]], the Rißbach flow direction having been reversed. The Isar water flows into the giant downpipes of the [[Walchensee Hydroelectric Power Station]]. 200 metres lower, the Walchensee Hydroelectric Power Station releases water into the [[Kochelsee]]. From here, it flows into the river Loisach, Isar's second most important tributary.

Not far down the Isar river is a large reservoir called [[Sylvensteinsee]] was created between 1954 and 1959 to make more energy generation possible and also to avoid flooding. It is located some 12&nbsp;km south of [[Lenggries]]. It has prevented the flooding of [[Munich]], for example in 1979, 1999, and most recently in 2005. At [[Bad Tölz]], the Isar leaves the [[Bavarian Alps]]. Bad Tölz marks the river's transit from its upper to its middle course.

The Isar river flows through a sub-alpine, [[glacial]] [[morainic]] landscape towards [[Wolfratshausen]]. Just north of the town the [[Loisach]] flows into the Isar. The Isar continues on to and through the [[Munich gravel plain]] which ends within the city limits of Munich. Further downstream, the river passes [[Freising]], then the [[Amper]] flows into the Isar, its most important tributary, at [[Moosburg]]. This is where the lower course of the Isar river begins.

Passing [[Landshut]], the river makes its way through the [[Tertiary Hills]] of [[Lower Bavaria]] all the way into the [[Danube]] river. The Isar river descends some 848m to flow into the Danube, about five kilometres away from [[Deggendorf]].{{citation needed|date=July 2016}}
