[1] In the early 1800s, King Kumwimbe of the Luba Kingdom created a client state that united the Hemba villages of the Lukushi River valley, and that played an important role in preserving Luba dominance over other small states in the region.

[2] In 1932 Geomines was building a reservoir on the Lukushi River to contain 10,000,000 cubic metres (350,000,000 cu ft) of water to support tin mining operations at Manono.

[3] A 1950 report on a campaign to eliminate malaria by spraying dwellings with DDT said the Lukushi River had been progressively silted up by tailings from mining operations.

[4] A 1981 USAID project examined agricultural activity around Manono and the Lukushi valley based on aerial photographs.

Part of the change could be attributed to wetter ground in the downstream regions, but the main factor seemed to be economic problems due to deterioration of the mines in Manono.
