The Kourou (in French pronounced as /kuru/) is a river in French Guiana, discharging into the Atlantic Ocean. It is 144km (89miles) long. The town of Kourou is located at its estuary, which is generally used as a pleasure port.
Like the river Amazon, it has brown, muddy waters due to sediments picked up from the forest. A great many different fish species live in the river and are used in the local diet.
Like many Guyanaise rivers, it is polluted by mercury, as a result of clandestine gold mining.
