ISERE [anc. Isara] , one of the See also:chief See also:rivers in See also:France as well as of those flowing down on the See also:French See also:side of the Alpine See also:chain. Its See also:total length from its source to its junction with the See also:Rhone is about 1So m., during which it descends a height of about 7550 ft. Its drainage See also:area is about 4725 sq. m. It flows through the departments of See also:Savoie, Isere and See also:Drome. This See also:river rises in the Galise glaciers in the French Graian See also:Alps and flows, as a See also:mountain torrent, through a narrow valley past See also:Tignes in a See also:north-See also:westerly direction to Bourg St See also:Maurice, at the western See also:foot of the Little St See also:Bernard Pass. It now bends S.W., as far as Moutiers, the chief See also:town of the Tarentaise, as the upper course of the Isere is named. Here it again turns N.W. as far as Albertville, where after receiving the Any (right) it once more takes a See also:south-westerly direction, and near St See also:Pierre d'Albigny receives its first important tributary, the Arc (See also:left), a See also:wild mountain stream flowing through the Maurienne and past the foot of the Mont Cenis Pass. A little way below, at Montmelian, it becomes officially navigable (for about See also:half of its course), though it is but little used for that purpose owing to the irregular See also:depth of its See also:bed and the rapidity of its current. Very probably, in See also:ancient days, it flowed from Montmelian N.W. and, after passing through or forming the See also:Lac du See also:Bourget, joined the Rhone. But at See also:present it continues from Montmelian in a south-westerly airection, flowing through the broad and fertile valley of the Graisivaudan, though receiving but a single affluent of any importance, the See also:Breda (left). At See also:Grenoble, the most important town on its See also:banks, it bends for a See also:short distance again N.W.

But just below that town it receives by far its most important affluent (left) the Drac, which itself drains the entire S. slope of the lofty See also:

snow-clad See also:Dauphine Alps, and which, 11 m. above Grenoble. had received the Romanche (right), a mountain stream which drains the entire central and N. portion of the same Alps. Hence the Drac is, at its junction with the Isere, a stream of nearly the same See also:volume, while these two rivers, with the See also:Durance, drain practically the entire French slope of the Alpine chain, the basins of the Arve and of the See also:Var forming the See also:sole exceptions. A short distance below Moirans the Isere changes its direction for the last See also:time and now flows S.W. past See also:Romans before joining the Rhone on the left, as its See also:principal affluent after the See also:Saone and the Durance, between See also:Tournon and See also:Valence. The Isere is remarkable for the way in which it changes its direction, forming three See also:great loops of which the See also:apex is respectively at Bourg St Maurice, Albertville and Moirans. For some way after its junction with the Rhone the See also:grey troubled current of the Isere can be distinguished in the broad and peaceful stream of the Rhone. (W. A. B.
