[4] Noxapaga River rises near Imuruk Lake and flows westward and southward, draining a total area of nearly 500 square miles (1,300 km2) at its junction with the Kuzitrin in the flats.
About 8 miles (13 km) north of its junction with the Kuzitrin, the Noxapaga flows near the northern edge of the valley lowland.
At this point, it receives a large tributary from the north, known as Turner Creek, where the settlement, Noxapaga, the recording office of the district, was located.
Two miles above Turner Creek, the Noxapaga occupies a rather broad canyon cut to a depth of 50 feet (15 m) or more in a gravel-covered plain above the valley floor.
