The Coalmol River is a major river of Tregueux, Zamastan, which flows from the Louise Mountains for 970 km (600 mi) southwest until it empties into the Cantalle Ocean at Tregueux and Shefbron. The river has a very high flow-rate and is bordered by both steep cliffs and widened and flat valleys suitable for agriculture. Tide waters flow in its fjord upriver as far as Walsboro (about 100 kilometres). Many whales breed in the cold waters at its mouth, making Chilport a popular site for whale watching and sea kayaking; sharks also frequent the depths of the river. The river originates from the Toile Glacier, which is formed over a large lake near Mount Utoi.
The Coalmol River was used as an important trade route into the interior for the First Nations people of the area. During the Adulan colonization of the region, the river became a major route for fur trade and tobacco agriculture. Beginning in the 19th century, the river was exploited for transport and power by the logging and pulp and paper industries. A dam on the upper Coalmol near Kipliers generates hydroelectricity for local industries, such as aluminum smelting and paper mills. Severe flooding of the river during Hurricane Alberta in 2001 devastated the region in one of Zamastan's costliest natural disasters. However, an unexpected effect of the flood was to cover the heavily contaminated sediments at the bottom of the river with 10 to 50 centimetres (3.9 to 19.7 in) of new, relatively clean sediments. Research has shown that the old sediments are no longer a threat to ecosystems.
