Sticky note: "Outlet of the Lukuga River from the Tanganyika. 27 April. Width of the river at the outlet about 100 metres, depth about 1 1/2 metres. Immediately after its exit it narrows to about 50 - 60 metres, at 1 1/2 - 2 km to about 40 metres. Its depth is then about 2 or 3 metres. At approx. 60 metres wide and 2 metres deep, the water had a velocity of 1 1/3 metres. This means that about 160 cubic metres per second flowed out of the lake. However, the Lukuga is currently a wide, fast-flowing river. If the water level of the lake sinks by about 1 1/2 - 2 metres, the Lukuga would certainly stop flowing. At the outlet point there is alluvial land; about 1 1/2 - 2 km downstream there is a reddish, fine-grained and thick-banked sandstone."
