The Aper Tief is a small river in the Lower Saxon communities of Apen in the Ammerland district and Detern in the Jümme district in the Leer district . It begins west of Apen at the confluence of the Große Süderbäke and the Große Norderbäke, runs roughly in an east-west direction and joins the Jümme south of the municipality of Detern .
The Aper Tief was channeled and expanded around 1845.
The Aper Tief is subject to the tides . The tidal range is about three quarters of a meter.
There are three retention areas at Aper Tief , which serve as flood protection. By relocating the dike on the left side, unregulated retention areas were created at Augustfehn and Vreschen-Bokel. At Augustfehn there is a retention area of around 1 million m³ on around 75 hectares. The area at Vreschen-Bokel is around 45 hectares. The two retention areas are subject to natural water dynamics and thus serve nature conservation. The area near Augustfehn is designated as a nature reserve " Aper Tief ", the area near Vreschen-Bokel is part of the nature reserve " Vreschen-Bokel am Aper Tief ". A regulated relief polder is connected to these two retention areas with the Polder Detern-Ore-Lowland .
The Aper Tief is crossed by bridges in four places: at Augustfehn, Vreschen-Bokel, Holtgast and Detern. At Augustfehn, the low was crossed by a bascule bridge, the Staaßenbrücke. The bridge was replaced in the early 1990s and moved to the Augustfehn Canal where it flows into the Aper Tief.
