Große Aa
# Große Aa

The Große Aa is a 35-kilometre-long (22 mi), right, eastern tributary of the River Ems in western Lower Saxony (Germany).

It begins in the Samtgemeinde Freren, near the quarter of Overwater, at the confluence of the Deeper Aa and Ahe rivers. From there is flows through Lünne westwards to Hesselte, where it is joined by the Speller Aa. From there on it runs parallel to the Dortmund–Ems Canal and discharges into the Ems 6 km (3.7 mi) south of Lingen, a few metres north of the mouth of the canal after the Gleesen locks.
