[10] There are often annual floods in the Malagarazi swamp due to fluctuations in the level of the Musasa River.

[11] In December 2021 the President of the National Platform for Risk Prevention and Disaster Management visited the site where the Kajeke River bed was being redeveloped in Gihanga Commune by Oxfam with European Union funding.

In March 2023 Gervais Ndirakobuca, Prime Minister of Burundi, visited the site to inspect the dam, which had been rehabilitated by the TUBEHONEZA project funded by the European Union.
