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, See also: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 .
