Niger Delta Coast

The Niger Delta is the world's third-largest delta: a vast network of distributary channels, mangrove swamps, tidal creeks, and barrier islands spreading across 70,000 square kilometres of the Nigerian coast. Tidal range at Bonny and Port Harcourt runs 1.5 to 2.2 m on springs — moderate mesotidal, with the tidal bore in some channels creating a visible wave front on the incoming flood. The creeks and distributaries are navigable year-round by shallow-draft vessels; tidal state governs passage through bar crossings where distributaries meet the Atlantic. The delta supports one of Africa's most productive artisanal fisheries, with tidal creek fishing a central part of life in riverside communities. The Niger-Delta has been an oil-producing region since the 1950s, and the infrastructure of that industry — flow stations, pipelines, flare stacks — sits alongside traditional fishing villages throughout the mangrove zone.
