The available hydro-climatic data obtained for the evaluation of trends in the basin were made between 1960 and 2002 water levels in the area. The data set for each station was analyzed using a second order polynomial curve. The findings revealed that the water levels varied from one part of the basin to another. Two locations showed rising trends in the measurable water levels from the early 1980s. For example, in Lai (Logone) a peak of about 230cm was reached around 1982. A gradual decline to less than 180cm then set in towards 2002, but did not reach as low as 160cm recorded in 1960. Therefore, acquisition of additional and more recent hydroclimatic data for effective predictive study as well as the restoration of the basin was recommendedenThesis
