Hehlenriede is a river of Lower Saxony, Germany. It flows into the Aller Canal near Gifhorn.
Investigations of the TU Braunschweig have shown that the area is particularly at risk of floods when there is continuous rain for around an entire day.
The Lower Saxony Water Quality Report from 2004 rates the chemical pollution of the Hehlenriede stream as moderately polluted along almost its entire length. The NLWKN's 2017 water quality map classifies its ecological potential as poor.
