The Seille (pronounced|sɛj) is a river in the French "région" of Lorraine, right tributary of the Moselle River. It is also known as the "Seille lorraine" or the "Grande Seille" ("large Seille"), to distinguish it from another Seille, a small tributary of the Saône.

It originates near Azoudange, in the département of Moselle. Leaving the Lindre lake, it skirts the town of Dieuze, and traverses Vic-sur-Seille and Nomeny, before flowing into the Moselle at Metz. It is 135 km long, and has a basin area of 1348 km². Most of its length is in the département of Moselle, except for the part between Aulnois-sur-Seille and Cheminot, which is in Meurthe-et-Moselle. The Seille also serves as the border between Moselle and Meurthe-et-Moselle from Chambrey to Aulnois-sur-Seille.

Upstream

Originating in the Pond region, the Seille then crosses Saulnois, a region in the South of Moselle. This section of the river is part of the "Parc naturel régional de Lorraine" ("Regional Natural Park of Lorraine"). The river then flows into a large valley, the ground of which is composed mainly of marl and clay. Since the Middle Ages, there has been much work performed on the Seille, in part to straighten it (to render it navigable), to drain the nearby swamps, and to limit flooding of adjacent low-lying areas.

Its linear course and the treelessness of its banks makes it of little interest to the landscape, and today the erosion of its banks poses problems. Despite this, the valley is of biological interest: salt water resurgences have led to the presence of various plant species that are usually confined to coast lines, including glasswort, "aster tripolium", and sea-spurreys.

As of 2004, work is being done on the river: the banks of the river are being reforested, and an oxygenation system is being installed.

The Seille has a number of tributaries, the most important of which are:
* the "Spin" and the "Verbach", in Dieuze (right bank)
* the "ruisseau de Videlange" (lit. "brook of Videlange"), near Mulcey (right bank)
* the "Nard", in Marsal (left bank)
* the "Petite Seille" (lit. "Small Seille"), in Salonnes (right bank)
* the "Loutre Noire" (lit. "Black Otter"), in Moncel-sur-Seille (left bank)

Downstream

Downstream, the Seille is much less straight, following a contorted path along the border of the département of Moselle.

This section of the river has comparatively few tributaries:
* the "Osson", at Ajoncourt
* the "ruisseau Saint-Jean" (lit. "St. John brook"), in Létricourt (right bank)
* the "ruisseau Saint-Pierre" (lit. "St. Peter brook")

Finally, in Metz, after passing the "Porte des Allemands" (a 13^th century castle, lit. "Gate of the Germans"), it flows into the right bank of the Moselle River.

Flora and Fauna

The river is classified as "Category II" (categories are based on types of fish), and is the habitat for a very large variety of fish.It is also home to a variety of other animals, such as otters, herons, and caterpillars.The Seille suffers from eutrophication.

Toponymy

Numerous towns and villages incorporate the name of the river into theirs. Some examples include: Aboncourt-sur-Seille, Aulnois-sur-Seille, Bey-sur-Seille, Brin-sur-Seille, Coin-sur-Seille, Haraucourt-sur-Seille, Mailly-sur-Seille, Malaucourt-sur-Seille, Moncel-sur-Seille, Morville-sur-Seille, Port-sur-Seille, and Vic-sur-Seille.The suffix "sur-Seille" means "on the Seille" in French, and the practice is analogous to the English place names that incorporate river names, such as Newcastle-upon-Tyne.
