The river's headwaters are in the reculée (blind valley) of Baume-les-Messieurs, approximately 10 km east of Lons-le-Saunier. 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, then Louhans and the Bresse area in the "départment" 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.

The upper part of the Seille is a tranquil trout stream that sometimes overflows its banks in the spring. The lower part, also prone to substantial flooding, is navigable for 39 kilometers from Louhans to La Truchère; there one can find catfish that have inhabited the river since the 1960s and that occasionally become very large. The river is known for, in the 1980s, having the largest catches of catfish in France (record: 2.20 m, 66 kg).

The Seille watershed covers 2300 km², containing some 600km of watercourses in three "départements": Jura, Saône-et-Loire, and Ain, thus being located in three administrative regions. A river contract for the Seille basin was put in place by the Saône and Doubs Mixed Syndicate in 2002, with financial assistance from regional and general councils, the Water Agency, and the State. The contract concerns water quality and the flooding of residential areas, which can affect more than thirty "communes": the three most affected regions being the Louhans metropolitain area, Bletterans, and Voiteur.
