History The district was established in 1972 by merging the former districts of Dingolfing and Landau (Isar). Its original name was Untere Isar ("Lower Isar"), but in 1973 it was renamed and got its present name. Geography The region is characterised by very plain countryside and several rivers running from southwest to northeast (towards the Danube). Most important rivers of the district are the Isar and the Vils. Economy The whole region depends on the automobile industry.
