evidence: Chiengi Boma was probably the first colonial post in what was to be called North-Eastern Rhodesia (it was still referred to as part of 'Zambezia' at the time), and was one of the most remote outposts of the British Empire, a lonely posting which sent more than one colonial officer mad.[1] For a number of years the boma was removed to the Kalungwishi River, and during this period the Belgian colonial authorities in Pweto, just across the border in DR Congo, controlled the northern end of the lake including the western extremity of Chiengi District, the so-called Lunchinda enclave west of the Lunchinda River. The British then re-established the boma at Chiengi but the eventual outcome of de facto Belgian control of the Lunchinda enclave led to it eventually being ceded to DR Congo by Zambia — see the article on the Luapula Province border dispute. [...] Chiengi is reached by a gravel road, frequently impassable in the rainy season, from Nchelenge and Kashikishi 100 km south (the same journey can be done by boat). From Chiengi a dirt track runs along the flat northern lake shore to Pweto in DR Congo. A new gravel road has been constructed north-east to the border, around the Chipani Swamp and east to Kasongola from where (in the dry season) tracks connect to Kaputa in Zambia's Northern Province.[5]
