Rivers in Accra gradually going extinct Self-inflicted disaster is looming around Klagon and Afienya in the Greater Accra Region because the flow of natural river bodies are being impeded by human activities. The gravity of the act emanates from the fact that these river bodies are receptacles for large volume of water collections from the Akwapim range and Accra plains respectively. The Mamahuma River, which crosses the Ashaiman Underpass-Lashibi road at Klagon in the Tema West Municipal Assembly (TWMA), has become blocked downstream before it empties into the Sakumo Lagoon. It has been observed that some faceless supposedly powerful persons have in a calculated fashion been transporting construction waste materials from elsewhere and dumping them into the river to impede its natural water course, whilst some portions have completely been blockedwith impunity.
