Jossa is a river of Hesse, Germany. It is a tributary of the Sinn, which in turn flows into the Franconian Saale shortly before the latter discharges into the Main at Gemünden am Main.
The Jossa has a length of 32.3 kilometres.
It originates at, an Ortsteil of Jossgrund. Here the Villbach is joined by the Lettgenbrunner Quelle. Since 2007, the place has been marked by a large boulder.[1]
The Jossa then flows southeast before turning northwards. Passing and (two other parts of Jossgrund) it gradually turns east north of, part of Bad Soden-Salmünster. Its northernmost point is near (part of Steinau an der Strasse) and it then flows southeast to discharge into the Sinn at Jossa, a part of Sinntal.
The Jossa and its tributaries drain an area of around 146.7 square kilometres.[2] It marks the border of the area that drains to the east towards the Sinn. To the west and north lies the Kinzig watershed.
Beavers have been successfully reintroduced since 1987/88 in the Jossa and Sinn valleys. From an original population of 18 beavers (from the Elbe river), their numbers have recently grown to more than 200.[3]
