Rivers

The confluence of two rivers, the Huisne and the Sarthe, dominated by a mound, is a great place to observe site, defense, transportation by water and the celebration of worship. After Caesar's victory over the Gauls, it is precisely this confluence, in a central position in the territories of Cenomani, that is chosen to become the capital. The Roman city flourishes overflowing on the right bank of the Sarthe. Observe the fountain of Hopiteau legacy of the Roman period. Sarthe rises out of the department to which it gave its name to Saint-Aquilin-de-Corbion, in the Orne, at an altitude of 252 meters.

After birth in the hills of the Perche, the river flows of the Northeast to the Southwest to Alençon, then she takes a south - south-east direction and crosses the Mancelles Alps by, a winding  and deep valley, not lacking picturesque (canoeing courses). Beyond Fresnay-sur-Sarthe, Sarthe flows slowly, lined with poplars, through Le Mans countryside, first south to downstream of Le Mans where it receives the waters of the Huisne, then to the west to Sablé-sur-Sarthe and again, south to the confluence of the river Mayenne, with which it forms the river Maine, north of Angers Ecouflant. Shortly before the meeting (about 4 kilometers downstream), the river Sarthe receives its main tributary, the river Loir, the water stream (317 km) is longer than hers (313 km). The watershed of the river Sarthe is particularly extensive - 16 374 yd - thanks to its numerous tributaries, especially the river Loir. It also has a larger catchment area (8270 km²) that his mother river (7864 km²).

The river Huisne rises in the hills of Perche, La Perriere (Orne department). After a course of 161 km, it comes together with the Sarthe in Le Mans. It is a tributary of the Sarthe on the left bank, so a sub-tributary of the river Loire threw the river Sarthe and then threw the river Maine.
