Seille

The Seille is a river originating in the Jura mountains in France. It is a left tributary of the Saône, joining it in the commune of La Truchère, in Saône-et-Loire. It is 100.5 km long.The river's headwaters are in the reculée of Ladoye-sur-Seille, approximately 8 km south of Poligny. It is joined by the Seille de Beaume, that springs in the blind valley of Baume-les-Messieurs, in Nevy-sur-Seille. From there it crosses the vineyards of the Jura department, irrigating the communes of Nevy-sur-Seille, Voiteur, and Arlay, before reaching the agricultural plain of Bletterans. It then passes Louhans and the Bresse area in the department of Saône-et-Loire, finally flowing into the Saône at La Truchère, a few kilometers south of Tournus. Near its mouth, the Seille forms a 3047 hectare network of ponds, dunes, and bogs, providing a habitat for a large number of migratory birds, including endangered species and rare plant species.
