The establishment of catchment management agencies goes beyond the involvement of governmental entities or the stipulations contained in regulatory structures and policies. A number of actors or stakeholders from both the governmental and non-governmental spheres are involved in establishing a CMA. Practices that are associated with CMA establishment often relate to personal experiences and the overall political landscape as well as administrative development trajectories. These are also context specifi c to the respective catchment. We refl ect on some of the administrative processes as a way to discern noticeable practices in the establishment of CMAs. Our case study material is the South African CMA establishment process to date. Some of the practices that come out strongly are human resource issues and fi nancial accounting practices that decision-makers need to consider when establishing CMAs. An appreciative relationship with key stakeholders, meeting them personally, is also crucial. The chapter is based on research commissioned and funded by South Africa's Water Research Commission between 2014 and 2016. The process of establishing the Flussgebietsgemeinschaft Elbe in Germany is also outlined to illustrate the similarities and differences in the experience of establishing a river basin organisation in a developed and developing country.
