The Seetal is a valley in the cantons of Lucerne and Aargau in Switzerland. The valley descends from south to north from near Eschenbach (in the canton of Lucerne) to Lenzburg (in the canton of Aargau), and is drained by the Aabach and the Ron. The valley is distinguished by Lake Hallwil and Lake Baldegg, from which it takes its name (Lake Valley).[1]
