The study of the effect of the Wolwedans Dam on the Great Brak Estuary and the development of the management plan to maintain a healthy environment yielded many interesting results. The general conclusion is that developments in a catchment, especially those affecting the runoff, can have serious effects downstream. The study also proves that detailed investigations can result in an effective management plan to maintain a healthy environment.
