The Jungnangcheon (Korean: 중랑천) is a tributary of Seoul's Han River.

Seoul Selection reports that there are some areas alongside the stream where rape flowers are visible in May.

Pollutants at the bottom of the riverbed contaminated the stream after a storm, and citizens called environmental authorities.

Uijeongbu city government reported its plan to build more ecologically-friendly sewage disposal plants.

Despite the likelihood that the water is not clean, many people fish in the river downstream from Uijeongbu.
