Ogunpa River

The Ogunpa River river system is a third-order stream with a channel length of 21.5 kilometres (13.4 mi) and a drainage basin covering 73.3 square kilometres (28.3 sq mi) draining the densely populated eastern part of Ibadan, Nigeria.

After about 10 hours of heavy downpour recorded as four times heavier than it was during the 1978 flood, the city of Ibadan was virtually left in ruins.

[4] Ibadan is one of many key regions in the globe where managing solid waste poses a serious threat to the environment and the general public's health.

The Ogunpa River, which flows through the city's core and is significantly polluted by solid waste, including plastics, bottles, and other non-biodegradable items, is one such example.

[6] Although the project was scheduled for completion in February 2003, some of the contractors working on the channelisation reportedly abandoned the site unfinished.
