Sungei Merah is situated on the eastern bank of the Igan
River, about 5km downstream from the confluence of the Rajang River.
The jetty is about 91km from the mouth of the Paloh River and about 116km
from the mouth of the Rajang River.
There is one 48.8m long wharf used primarily
for the handling of fuel oil in bulk. The wharf is limited to vessels
of 75m length and with draughts of 4.6m because of the narrowness
of the river.
