Overview

Excerpt from Journal of the Royal Colonial Institute, Vol. 39: No. 2, Session 1907 1908 Lake Nyasa and the Shire Valley form a portion of one of the lengthiest rifts in Africa; it may be said to commence at the junction of the Shire with the Zambesi, and to run without inter ruption to the north end of Lake Nyasa. Here the line Of rift is shifted a little to the north, and is carried on by the Lake Rukwa Valley. It is continued again by Lake Tanganyika; and, with a few breaks further north, by Lake Kivu and the Albert Edward and Albert Nyanzas to the Nile. Lake Nyasa is now lower by some feet than it has been for twenty-five years. All round the margin of the lake, moreover, are to be seen beach marks far above the present water level, which show that at previous periods the water has been much higher than it has been at any time within the knowledge of Europeans. Last year the lake fell to such an extent that at the end of the dry season it ceased overflowing at its outlet (the Shire River). Not only so, but at the commencement of the rains in November, when local streams began to throw their water into the Upper Shire, this portion of the river for some weeks ran into Lake Nyasa, instead of carrying Nyasa's water southward. As banks of sand and mud began to appear at the exit of the river, they were quickly clothed with grass, reeds, and other vegetation, thus closing up still more the lake's outlet.
