At a length of 53.4 km (33 miles), it was believed to be the longest until it was discovered that the Rio Minho was 92.8 km long. Its name refers to the darkness of the river bed caused by thick layers of decomposing vegetation. Over 100 species of birds have been recorded in the Black River morass. The river's source is the Cockpit Country where it runs underground before emerging north of Siloah on the southern fringe Cockpits (18.1895534°N 77.6833069°W). Immediately after its emergence, the river meanders gently through the cane fields of the Appleton Estate. It receives a boost fom the One Eye River which is a continuation of the larger Hectors River which forms the Trelawny-Manchester border. Approaching Maggoty its speed increases and occasional rapids occur.
