There is less information available on water level in the Lake Chad basin. The absence of adequate field observation networks in basin countries means that there is very little data available on the level and variation of groundwater. In the period from 2007 to 2019, work from the CBLT-BGR project provided some insight into the groundwater level and flow in the Chari-Logone system and the aquifers shared by Chad and Cameroon. The water level was studied in open wells and piezometers and some piezometers have been equipped with automatic data loggers.
