context_page_description: The Moselotte is a river in Lorraine, in the French department of Vosges. It is a direct right tributary of the Moselle, and thus a sub-tributary of the Rhine.
context_section_description: While in 2005, the water quality of the Moselotte was classified as category 1B, or "bonne" (good), the situation deteriorated somewhat in 2006, when the Rhine-Meuse water agency concluded that the river water analysed at the level of Autrive was now only "passable", or category 2. The reason was a highly depressed rate of oxygen saturation (also classed as "passable"), which had gone from 76% in 2005 to 69% in 2006. The chemical oxygen demand, at 6.5 mg/l in 2006, was still classified "bonne". The ammonium ion level was measured at 0.09 mg/l, which was classed as "excellent".
