4. Lake Chad
This is a declining lake in the continent of Africa. It is found in central Africa, located mainly in the far west of Chad and Cameroon. Bordering on Northeastern Nigeria It was recorded as the largest and shallow lake in the continent of Africa attaining a depth of 285 meters and covered 150 sq meters. But with retreat of the shoreline and the sand dunes submerged to the lake make it decline.
Due to the shrinkage of the lake, habitant for species in this lake is becoming destructed. Species tend to adopt the life of a river as water in the lake is reduced. It only gets water from Chari River which is the largest source of water to the lake and this lake does not have the outlet.
The water reduction in this lake occurs through use of water by the community on their activities and also by evaporation. This lake is providing water to more or less than 20million people living in the surrounding countries such as Chad, Cameroon, Nigeria and Niger. It plays a role economical and social in the people who live around the lake.
Image 1 shows the location of Lake Chad and the features around it. Pictures were taken in 2D dimension .with the compass facing North east in the co-ordinates of 13° 07´ 46.12˝ N and 14° 31´ 14.37˝ E.
This image was taken in 2D dimension which can show the coverage of the lake and its shrinkage. This can be seen by the swamps that are developing around the lake. The image was taken with the compass facing North east in the co-ordinates of 13° 04´ 45.03˝ N 14° 20´ 56.72˝ E.
Image 3 was captured in close range using 2D dimension. This image can reveal the area which was covered by the lake in the previous time before the shrinkage. It was taken with compass facing south west in the co-ordinates of 13° 20´ 58.30˝ N and 14° 22´ 50.66˝ E.
The image shows the tributary that support the lake with water. It was taken with the compass facing south west in the co-ordinates of 12° 51´ 33.56˝ N and 14° 34´ 41.22˝ E.
