(p7) After a detailed desciption of the Senegal River, its valley and tributaries, the report mentions that Kayes is at an altitude of only 23m, even though it is nearly 1000km from the ocean. That explains why the river is so flat and tends to silt up.

(p14) Statistics on the level of the Senegal River (1908- 1921), based on information collected by the Chemin de Fer Kayes-Niger at Galougo. Days that the river was at least 1.5 meters deep and flowed at least 300 cubic meters per second.

(p20) The author explained why he thought that the Senegal River could not be used in the same manner as the Nile River.

The relatively warm winter makes it impossible to grow oat and wheat, ...
(p21) and the irregular floods mean that the amount of irrigated land varies greatly from year to year.
